Toyota MR2 buyer's guide

The Toyota MR2 brought the mid-engined sports car to ordinary buyers. The name stands for Mid-ship Runabout 2-seater, and there were three quite different generations: the wedge-shaped AW11 coupe of 1984 to 1989, the larger and faster SW20 of 1989 to 1999, and the open ZZW30 MR2 Roadster, sold in Japan as the MR-S, from 1999 to 2007.

People buy them for the driving position, the balance of a mid-mounted engine and the fact that Toyota mechanicals are generally tough when serviced. The weak points are well known: rust on the first two generations, cooling systems that are awkward to bleed, and on early Roadsters an engine problem linked to the exhaust pre-catalysts. Many cars have been modified, and a large share of those for sale in the UK are Japanese imports, so identity and history need checking.

This guide is for buyers looking at an MR2 at a dealer, privately or at an auction such as Mathewsons in North Yorkshire, and for owners preparing to sell. It does not cover repairs: where work is needed, a specialist can advise.

The Toyota MR2 (AW11, SW20 and ZZW30 Roadster) in brief

Toyota showed the SV-3 concept at the 1983 Tokyo Motor Show, and the production AW11 went on sale in Japan in 1984 and in the UK in 1985. Lotus is widely credited with input on the suspension. UK cars had the 122bhp 4A-GE twin-cam and a five-speed manual, while Japan also had a 1.5-litre economy model and, from the mid 1980s, a supercharged 1.6. Many supercharged cars have since come to the UK as imports.

The AW11 was facelifted in late 1986, and enthusiasts call the two types Mk1a and Mk1b. The later car has a body-coloured front bumper insert, a stiffer engine block with red lettering on the cam cover, uprated suspension and brakes, and from around 1987 a stronger C52 gearbox in place of the C50. A T-bar roof with two removable glass panels joined the range in the mid 1980s. Most UK cars are the later type, and rust is the main concern on all of them.

The SW20 arrived in October 1989 and reached the UK in 1990. It was bigger and heavier, with a 2.0-litre engine. The UK range was the 119bhp MR2, also offered as an automatic, and the 158bhp GT and GT T-bar. The 3S-GTE turbo, with about 225PS in early Japanese form, was sold in Japan and the US but never officially in the UK, so every UK Turbo is an import.

Owners divide the SW20 into revisions. Rev 2, from December 1991, brought 15-inch wheels, larger brakes and suspension geometry changes to make the car more forgiving at the limit. Rev 3, from late 1993, brought a 3S-GE of about 173bhp in UK form, round rear lamps and colour-coded trim, with the Japanese turbo rated at 245PS. Rev 4 from June 1996 and Rev 5 from December 1997 were smaller updates, though Rev 5 Japanese cars gained a VVT-i 3S-GE of about 200PS. Rev 3 and later are generally regarded as the better cars to drive.

The Roadster was lighter and simpler. It was unveiled at the 1999 Tokyo Motor Show and reached the UK in 2000 with the 138bhp 1.8-litre 1ZZ-FE and a five-speed manual, with a clutchless SMT sequential gearbox following in 2001. There is no rear boot: luggage goes behind the seats and in a small space in the nose.

A facelift for late 2002, often called the 2003 car, brought revised lights, extra body bracing, revised suspension, 16-inch rear wheels and a six-speed gearbox in manual and SMT forms. Toyota also revised the engine and pre-catalysts, as early cars had become known for pre-catalysts breaking up and damaging the engine. The run ended in 2007, with the last 300 UK cars sold as the TF300.

Versions to know

Version	Years	What to know
AW11 Mk1a	1985 to 1986 (UK)	Original UK specification with blue cam cover lettering, black front bumper insert and C50 gearbox. Harder to find than the later car.
AW11 Mk1b	Late 1986 to 1989	Body-coloured bumper insert, red cam cover lettering, stiffer block, uprated suspension and brakes, and the C52 gearbox from around 1987. Early facelift cars can mix parts. T-bar versions often have leather trim.
AW11 supercharged (import)	Mid 1980s to 1989	4A-GZE of about 145bhp, never sold new in the UK. History and import paperwork matter.
SW20 Rev 1	Late 1989 to December 1991	UK MR2, automatic, GT and GT T-bar on 14-inch wheels. Japanese Turbos with about 225PS. The most demanding SW20 at the limit.
SW20 Rev 2	December 1991 to late 1993	15-inch wheels, larger brakes and revised suspension geometry. A well kept Rev 2 can be a better buy than a tired later car.
SW20 Rev 3	Late 1993 to June 1996	About 173bhp in UK GT form, round rear lamps and colour-coded trim; Japanese Turbo at 245PS. The UK range had narrowed to GT and GT T-bar.
SW20 Rev 4 and Rev 5	June 1996 to 1999	Mostly cosmetic updates. Rev 5 Japanese cars gained the VVT-i 3S-GE of about 200PS, never sold in the UK.
SW20 Turbo (import)	1989 to 1999	3S-GTE with the stronger E153 gearbox, offered with a limited-slip differential. Check import papers, specification and modifications.
Roadster, pre-facelift	2000 to 2002	Five-speed manual or SMT, 15-inch wheels all round. Most at risk of pre-catalyst failure.
Roadster, facelift and TF300	Late 2002 to 2007	Six-speed manual or SMT, 16-inch rear wheels, extra bracing and revised pre-catalysts, which reduce but do not remove the risk. The TF300 was the final 300 UK cars, with special trim.
MR-S (Japanese import)	1999 to 2007	Japanese-market Roadster. Specification varies, and some early imports were less well rustproofed than UK cars.

Pros and cons

Pros	Cons
Mid-engined balance and a low driving position in an otherwise straightforward car. Toyota engines and gearboxes are durable when serviced on time. The AW11 is light, revs freely and has fuel injection rather than carburettors. The SW20 is quick in GT form, and the imported Turbo is fast by any standard. The Roadster is light, economical and uses a timing chain rather than a cambelt. Many Japanese imports widen the choice, especially for Turbo and supercharged cars. An established UK club and a network of independent MR2 specialists.	AW11 and SW20 cars rust, especially in the sills, arches and boot floors. Long coolant pipes between the front radiator and the engine make bleeding awkward, so airlocks and overheating occur. Tight engine access makes AW11 and SW20 cambelt changes easy to put off. T-bar roofs are prone to leaks, leading to damp interiors and rust. Early Roadsters can suffer pre-catalyst failure that damages the engine. Many cars have been modified, lowered or engine-swapped, sometimes poorly. Limited luggage space, especially in the Roadster.

Myths and realities

Every SW20 is a snap-oversteer widow maker.

Early cars, especially Rev 1 Turbos on worn tyres, can catch out an unprepared driver. Rev 2 changes made the car more forgiving, and specialists say a well set up car on matched tyres behaves like any mid-engined sports car. Lifting off mid-corner is still a bad idea.

A Toyota engine never needs looking at.

The engines are durable, but they need regular oil changes, cambelts on time on the AW11 and SW20, and a properly bled cooling system. Neglect still causes head gasket and bearing failures.

Japanese imports never rust.

Cars kept in Japan avoided road salt and are often more solid, but some were less well rustproofed than UK cars and can deteriorate quickly once used here. Judge each car on what you can see underneath.

Pre-cat failure only affects Roadsters with huge mileage.

The risk is linked to pre-2003 build and oil consumption, not just mileage. A low-mileage early car with original pre-catalysts and no records still needs checking.

What to check

Bodywork and structure: AW11

Rust is the AW11's main weakness, and repairs can cost more than a project is worth. Take a torch, a magnet and a mat to lie on.

Sills and jacking points: look behind the plastic sill covers and check the jacking points from underneath.
Front and rear wheel arches, including the whole rear arch and the rear valance.
Bottoms of the A and B posts, which are costly to repair.
Front crash bar behind the bumper and the front slam panel seams.
Front luggage area: the spare wheel well, boot floor and liner seams.
Around the windscreen and front of the roof, where blocked sunroof or T-bar drains let water sit.
Floorpan and rear subframe mounting points, plus door bottoms and lower front wings.

Bodywork and structure: SW20

The SW20 rusts in different places from the AW11, and some of the worst areas are hidden.

Rear sills: sound-deadening foam inside traps water and rots them from within. Look for bubbling and ask whether the foam has been removed.
Rear wheel arches and inner arches, especially on cars used through UK winters.
The two bracing bars under the rear, often called cancer bars, which rust where paint cover is poor.
Inner headlamp brackets, the front crossmember, door bottoms and the boot floor under the carpet.
Paint: red cars fade badly, and some black and green metallic finishes lose their lacquer.
Uneven panel gaps, overspray or mismatched colour, which point to accident repairs.

Bodywork and structure: Roadster

Body rot is less of a worry than on the coupes, but the rear subframe and hood drains need checking.

Rear subframe, which carries the engine and rear suspension: its coating breaks down near the exhaust and it can rot badly. On most cars it hides behind a plastic undertray.
Floors under the carpets, where blocked hood drains let water in.
Panel gaps front and rear: outer panels bolt on, and uneven gaps suggest crash repairs.
Front inner wings, lower bulkhead and suspension mountings, especially on Japanese imports.
Alloy wheels, which pit and corrode.

Engines

All three engines are durable with regular servicing, but each has known faults. Ask for a cold start if you can.

AW11 and SW20: ask when the cambelt was last changed. On the AW11 it is due every 60,000 miles or about every five to six years.
All three: check coolant strength and colour, the long pipes to the engine, the radiator for front-end damage, and that the fan cuts in.
Oil leaks: AW11 sumps can become porous, and distributor O-rings and cam cover gaskets leak on the AW11 and SW20.
Signs of head gasket failure after overheating: white smoke, bubbles in the coolant, or oil and coolant mixing under the filler cap.
AW11: tapping from the top of the engine suggests the valve clearances need attention; a high idle can be a sticking idle control valve.
SW20 Turbo: full boost should arrive around 3,000rpm. Smoke, a whistle or late boost suggest turbo wear. Ask whether the coolant hose near the exhaust manifold has been renewed, as it can burst at high mileage.
Roadster: blue smoke on overrun, rising oil use and a lambda warning light can point to pre-catalyst failure. A compression test is wise, especially on pre-2003 cars, along with paperwork for any pre-cat removal or replacement.

Gearbox and drivetrain

Manual gearboxes are strong, but synchromesh wear and modified power show up here.

AW11: check it does not jump out of fifth on a faster road, most associated with the earlier C50 gearbox, and listen for crunching into first or second.
SW20: the S54 gearbox on non-turbo cars is robust. Turbos use the stronger E153, costly to replace if damaged; listen for whine or clunks from the differential.
Roadster SMT: changes should be smooth and warning lights should go out. Jerky changes can mean actuator, pump or control unit faults, which are costly.
Clutch on all three: check for slip under load.
Automatics on the AW11 and SW20: test every position stationary and on the move.

Suspension, steering and brakes

Worn bushes, seized rear brakes and wrong tyres change how these cars drive more than buyers expect.

Tyres: SW20s and later Roadsters run wider tyres at the rear. Check sizes are correct, matched across each axle and from a reputable brand.
Uneven tyre wear, suggesting worn bushes or poor alignment, often after lowering.
Clonks over bumps from worn bushes or drop links.
Rear brake calipers that seize, and on the Roadster handbrake cables that stick on little-used cars.
Roadster: notchy steering suggests wear in the column joint. SW20: check the power steering warning light goes out.
Lowered or coilover cars: check the work looks professional and ask what was fitted.

Electrics, roofs and interior

Electrics are mostly reliable, so faults usually come from age, water or poor aftermarket wiring.

Pop-up headlamps on the AW11 and SW20 should rise and fall together and smoothly.
Electric aerial on the AW11 and SW20, a known weak spot that sticks.
AW11: heater fan speeds (the resistor pack fails) and the driver's window switch pack, which is hard to find.
SW20: check the battery holds charge, as alternators suffer from oil leaks and water. Look for spliced wiring from aftermarket audio.
T-bar cars: look for staining and a musty smell, and check the seals.
Roadster hood: check for tears and cracks in the glass rear window, and that it folds and latches properly.

Paperwork, imports and originality

With so many imports and modified cars about, the paperwork tells you what you are really buying.

Check the chassis number on the car against the V5C and any import documents.
For an import, compare the build date with the date of first UK registration on the V5C.
Imports may have speedometers in km/h, radios that do not suit UK frequencies and different equipment from UK cars.
Service records showing oil changes, cambelt dates and Roadster pre-catalyst work.
Online MOT history, to check mileage and recurring corrosion advisories.
Declared modifications such as engine swaps, turbo upgrades and lowered suspension, which your insurer will need to know about.

On the test drive

Start from cold and watch for blue or white smoke, then let the car warm up fully to see that the temperature stays steady.
Check the heater blows hot, as poor heat can point to an airlock or, on a Turbo, a failed coolant hose.
On an AW11, hold fifth gear on and off the throttle to check it stays in gear.
Change down briskly through the gears to test the synchromesh.
On an SW20 Turbo, check boost builds cleanly with no smoke or whistle.
On an SMT Roadster, try changes in traffic and at higher revs, and watch for warning lights.
Brake firmly on a clear straight road: the car should stop straight, and nothing should drag when you pull away.
After the drive, look for fresh oil or coolant leaks.

Buying at auction

MR2s of all three generations appear at UK auctions, including regional sales such as Mathewsons in North Yorkshire. Imports and modified cars are common, and you will usually have less time with the car than in a private sale, so use the viewing days well.

What you can check in viewing week

Look underneath with a torch at the sills, arches, jacking points and whatever you can see of a Roadster's rear subframe.
Use a magnet on the sills, arches, lower wings and around the windscreen for filler.
Check the chassis number against the V5C and the catalogue, and look at any import documents.
Check coolant colour and level, oil condition and for leaks, and on a coupe the spare wheel well.
Lift the carpets where you can and feel for damp on T-bar and Roadster cars.
If start-ups are allowed, listen for rattles, watch for smoke and check warning lights go out.

What you usually cannot do

You usually cannot drive the car, so gearbox, SMT, boost, brakes and handling remain unknown.
You usually cannot put the car on a lift, so areas such as the Roadster subframe stay out of view.
You cannot run a compression test or see the engine get fully hot.
You cannot tell whether a roof leaks without rain or a hose.

Tips

Read the catalogue critically. Recommissioned or fresh MOT means little without receipts. Look for what is missing, such as no cambelt date or no mention of pre-catalyst work.
Check whether the car is described as a UK car or an import, and that the paperwork agrees. Be wary of a Turbo or supercharged car described only by its badges.
Remember the buyer's premium and any fees on top of the hammer price, and read the terms before you bid.
Set your limit before the sale, allowing for likely work such as a cambelt, tyres or rust repair, and stick to it.
Arrange transport home before you bid. Do not assume a car you have not driven is roadworthy, and check insurance and tax if you plan to drive it.

What makes one more desirable

Structural condition comes first on AW11 and SW20 cars: documented rust repairs and solid sills matter more than shiny paint.
Originality is increasingly valued, and unmodified cars are becoming harder to find.
AW11 Mk1a cars with the black bumper insert are less common, and supercharged imports attract strong interest.
Among SW20s, Rev 3 and later cars are generally preferred, and genuine Turbo imports with clear history attract the most attention.
For the Roadster, facelift cars with records of pre-catalyst work, a factory hardtop or TF300 status add to buyer interest.
A full service history, few owners and a known UK history or clear import record add to buyer confidence.

Selling a Toyota MR2 (AW11, SW20 and ZZW30 Roadster)

Buyers know where MR2s rust and which engine faults to look for, so a car with clear evidence on those points sells more easily.

Preparing the car

Clean the underside, arches and engine bay so buyers can see the sills, subframe and any leaks.
Fix small faults that put buyers off, such as sticking headlamps or warning lights, using a specialist where needed.
Have the car serviced and make sure it reaches temperature without trouble.
Sort roof leaks on T-bar cars and blocked drains or tears on Roadsters, and fit matched, correctly sized tyres.

Paperwork

V5C in your name with the correct chassis details.
Service records in date order, with cambelt dates or Roadster pre-catalyst work clearly shown.
Receipts and photographs for rust repairs.
Import documents for a Japanese car.
A list of modifications with dates, parts and who did the work.

Where to sell

Club classified adverts, where buyers know the model.
Specialist MR2 and Japanese car dealers, by sale or part exchange.
Classic car auctions, including regional sales such as Mathewsons, where the seller's commission and entry terms should be checked first.

Writing the description

State the generation, revision or facelift status, engine, gearbox, roof type and whether it is a UK car or an import.
Be honest about rust and repairs: what was done, when and by whom.
Declare modifications, especially engine swaps, boost changes and lowered suspension.
Photograph the sills, arches, underside and engine bay as well as the outside.

Living with one

Mechanical parts are shared with other Toyotas and generally easy to find, though some AW11 trim items are scarce.
Independent MR2 specialists support all three generations, and the club is a good source of advice.
Servicing is simple apart from engine access. Regular oil changes matter, and AW11 and SW20 cambelts must be done on time.
Luggage space is limited: the coupes have small front and rear compartments, and the Roadster a bin behind the seats.
Early AW11s are now passing 40 years old and may qualify for historic vehicle tax. Eligibility runs from the build date, so check this on an import. An annual inspection is wise even if the car is MOT exempt.
Classic insurance with an agreed value and limited mileage is widely available. Tell the insurer about modifications and whether the car is an import.

Questions people ask

Where do Toyota MR2s rust?

On the AW11, the sills, jacking points, arches, A and B posts, crash bar, front boot floor and windscreen surround. On the SW20, the rear sills, rear arches, under-car bracing bars and door bottoms. On the Roadster, mainly the rear subframe and floors under blocked hood drains.

Which MR2 generation should I buy?

The AW11 is the lightest and most classic in feel, but rust is the biggest risk. The SW20 is the fastest, especially as a Turbo import, and Rev 3 or later is usually preferred. The Roadster is the open car and the easiest to live with, provided the pre-catalyst issue has been dealt with.

What is MR2 Roadster pre-cat failure?

The ceramic pre-catalysts in the exhaust manifold can break up, and the debris can damage the engine bores. Pre-2003 cars are most at risk. Signs include rising oil use, blue smoke and a lambda warning light.

Was the SW20 MR2 Turbo sold in the UK?

No. Toyota GB sold the non-turbo MR2, GT and GT T-bar. Every UK Turbo is an import, so check the import papers, history and specification.

What are the SW20 revisions?

Rev 1 runs to December 1991, Rev 2 to late 1993, Rev 3 to June 1996, Rev 4 to December 1997 and Rev 5 to 1999. Rev 2 revised the suspension, wheels and brakes, and Rev 3 brought more power and styling changes.

Is the MR2 reliable?

Generally yes, if serviced. The weak points are rust on the first two generations, cooling airlocks, cambelt neglect, Turbo wear on hard-driven imports and pre-catalyst failure on early Roadsters.

Is an MR2 a good first classic?

It can be. Mechanical parts are easy to find and the engines are tough. If unsure, have a specialist check the structure on an AW11 or SW20, and the engine and subframe on a Roadster.
