MG MGF and MG TF buyer's guide

The MGF brought MG back to volume sports car making. Launched in 1995, it was a two-seat roadster with its engine behind the seats, Hydragas suspension and a 1.8-litre Rover K-series engine. In 2002 it was reworked as the MG TF, with steel coil springs, and sold until MG Rover collapsed in 2005. After Nanjing bought the assets, a lightly revised TF went back into production at Longbridge in 2008, starting with the LE500.

People buy them for the mid-engined layout, the folding hood and the MG badge in a car that is still easy to use. Parts supply is good and the owners' network is strong. Many cars have also been run cheaply, so the cooling system, the suspension and the steel underneath need careful checking.

This guide is for buyers at a dealer, privately or at an auction such as Mathewsons in North Yorkshire, and for owners preparing to sell. It covers what to look for, not how to fix it.

The MG MGF and MG TF in brief

The MGF went on sale in 1995. Its 1796cc K-series engine sat behind the seats, driving the rear wheels through a five-speed PG1 gearbox, and the suspension used Hydragas, a nitrogen-over-fluid system also used on the Rover Metro. For buyers the layout matters: the radiator is at the front and the engine at the back, so coolant runs through long pipes under the car.

The 1.8i had about 118bhp. The VVC, released in early 1996, used variable valve control for about 143bhp and had a lower final drive. Not every early 1.8i had electric power steering, so check what the car you are viewing has.

A late 1999 update for the 2000 model year brought new seats, a new centre console, revised power steering and new wheels. It also brought the Steptronic, a CVT automatic with stepped manual shifts by lever or steering wheel buttons, offered only with the 1.8i. In 2001 came a cheaper 1.6 and the Trophy 160, with a 160PS VVC engine, lowered and stiffer suspension, uprated brakes and aero add-ons.

The MG TF replaced the MGF in early 2002. Hydragas gave way to steel coil springs, the body was strengthened, the steering quickened and the front restyled. The range was named by power: TF 115 (1.6), TF 120 Stepspeed (1.8 automatic), TF 135 (1.8) and TF 160 (1.8 VVC). Early cars ride firmly; for the 2005 model year the suspension was softened and a heated glass rear window fitted to the hood. Production stopped when MG Rover collapsed in April 2005.

Nanjing bought most of MG Rover's assets in July 2005. After delays during its merger with SAIC, series production of the TF began at Longbridge in August 2008 under MG Motor UK. The first 500 cars were the LE500, followed in 2009 by the cheaper TF 135 and the 85th Anniversary. These cars use the N-series engine, a development of the 1.8 K-series with a revised head gasket, and many major parts were made in China. Sales were small, and Longbridge production had stopped by 2011.

Versions to know

Version	Years	What to know
MGF 1.8i	1995 to 2002	The original model with about 118bhp and Hydragas. Not all early cars have power steering. Early cars have two coil packs with long leads, more exposed to water from the engine cover vents.
MGF VVC	1996 to 2002	About 143bhp, revs higher, lower final drive. A rattle from the right-hand side of the engine can mean wear in the variable valve control mechanism, a costly repair.
MGF facelift (MY2000)	Late 1999 to 2002	New seats, centre console and wheels, revised power steering. Later cars have coils on top of the engine, less vulnerable to water.
MGF Steptronic	2000 to 2002	CVT automatic with stepped manual mode, 1.8i only. Slower and thirstier than the manual and sensitive to the correct fluid.
MGF 1.6i	2001 to 2002	Cheaper entry model of about 110bhp, identified by unpainted black door handles and side intakes.
MGF Trophy 160	2001 to 2002	The most powerful MGF: 160PS VVC engine, lowered and stiffer suspension, larger front brakes and aero add-ons. Check its specific suspension parts carefully.
MGF special editions	1998 to 2001	Abingdon (1998), 75th anniversary (1999), Wedgwood (2000) and Freestyle (2001). Mainly paint, trim and wheel packages.
MG TF 115, 135 and 160	2002 to 2005	Coil springs, stronger body, quicker steering, new nose. The 135 was the most popular; the 160 uses the VVC engine with 304mm front discs and AP Racing four-pot calipers. Pre-2005 cars ride firmly.
MG TF 120 Stepspeed	2002 to 2005	The 1.8 with the CVT automatic. Fluid type and gearbox behaviour need checking.
MG TF special editions	2002 to 2005	Sprint, Cool Blue, SunStorm, 80th Anniversary and Spark, mostly cosmetic packages.
MG TF 2005 model year	Early 2005	Softer suspension and a heated glass rear window, built briefly before the collapse.
MG TF LE500	2008 to 2009	The first 500 relaunched Longbridge cars: 135PS N-series engine, five-speed manual, leather, air conditioning, hardtop and rear parking sensors, with the softer late suspension.
MG TF 135 (MG Motor UK)	2009 to 2011	Mechanically the same as the LE500 with a lower specification.
MG TF 85th Anniversary	2009	TF 135 mechanicals with Bilstein dampers, thicker Eibach anti-roll bars and bespoke colours and trim.

Pros and cons

Pros	Cons
Mid-engined, rear-wheel-drive layout with balanced, approachable handling. Good parts supply for service items, trim and body panels, with many parts shared with other Rover models. Active, knowledgeable owners' clubs and a network of MGF and TF specialists. The PG1 manual gearbox is well proven and durable. The MGF's Hydragas gives a supple ride when it is in good order. The TF's steel springs avoid the ageing Hydragas issue altogether. The VVC and TF 160 engines rev freely and give strong performance for the size.	The K-series has a small coolant capacity and long coolant pipes, so any loss of coolant can lead to overheating and head gasket failure. Hydragas units are no longer made new; the MGF relies on re-gassing, used units or conversions. Front and rear subframes and the sills can rust from the inside where you cannot easily see. Water leaks into the cabin are common, especially at the front of the doors. The CVT automatics are slower, thirstier and sensitive to the wrong fluid. Pre-2005 TFs ride firmly, and the electric power steering can feel vague or develop faults. Engine access is tight, which makes routine jobs such as cambelt changes more involved.

Myths and realities

Every K-series will blow its head gasket.

Failures usually follow coolant loss and overheating. Many cars have had an improved multi-layer steel gasket, metal dowels and new coolant pipes. A car with records of that work is a different proposition.

Hydragas cannot be fixed.

Units can be pumped up and re-gassed, and specialists offer re-gassable units. New original units are no longer made, so a well maintained system matters more each year.

The TF is just an MGF with a new nose.

It has steel coil springs, a strengthened body and quicker steering, and drives differently, with a firmer ride before 2005.

Later Longbridge TFs have nothing in common with the originals.

They are a development of the same car, with an N-series engine derived from the K-series and the same PG1 gearbox, assembled at Longbridge with many parts made in China.

A special edition is always the one to buy.

Most are trim and paint packages. A sound standard car with history beats a tired special edition. The Trophy 160, LE500 and 85th Anniversary have real specification differences.

What to check

Bodywork and structure

The body was well rust-proofed, but corrosion now appears in hidden places. Take a torch, a magnet and a mat.

Front and rear subframes and their mountings: heavy rust here is a serious problem and a reason to walk away unless you accept major work.
Sills, especially where they meet the rear wings. Blocked drain holes let them rot from inside, a common MOT failure.
Side air intakes behind the doors, where dirt collects behind the mesh and stone chips start rust.
Leading edges and arches of the front wings.
Hollow front lower wishbones, which can rust.
Under the front bonnet for crash repair: uneven gaps, overspray or rippled inner panels.
Footwells under the carpets for damp and rust from water leaks.

Engine and cooling

The K-series has a small coolant capacity and long pipe runs, so it has little margin if coolant is lost. Check fluids before the engine runs.

Coolant level and condition in the expansion tank: clean, at the correct level, with no oily film.
Creamy deposits in the tank or under the oil filler cap can mean gasket failure, though short trips cause condensation that looks similar.
Ask whether the head gasket has been replaced, with what type, and whether the plastic locating dowels were changed for metal ones. Receipts should say.
Coolant pipes under the car: original steel pipes corrode. Stainless replacements are a good sign.
Radiator at the front: look through the intake under the number plate for leaks or crumbling fins.
Temperature gauge should rise steadily and settle. Steam from the rear or a sweet smell are warning signs.
Rattles at start-up can mean loose camshaft bolts; on a VVC, a right-hand side rattle can mean VVC mechanism wear.
Cambelt: replacement is usually due at 60,000 miles or four to five years. No proof means assume it is due.
Misfires or poor cold starting on early MGFs can come from water reaching the coil packs.

Gearbox and drivetrain

The PG1 manual is durable; the CVT automatics need a careful check.

Manual: a long but precise change. Sloppiness or difficulty finding gears usually means worn selector cables or linkages.
Clutch and handbrake cables are sensitive to adjustment: check for slip, judder and that the handbrake holds on a slope.
Steptronic and Stepspeed: take-up should be smooth with no shudder, flare or clunks. A slightly slipping feel is normal for a CVT.
Ask what fluid a CVT has had; the wrong fluid can damage it, and repairs are costly.
Try the stepped manual mode by lever and steering wheel buttons.
Listen for wheel bearing drone that rises with speed.

Suspension, steering and brakes

Hydragas and steel springs need different checks, but both cars are sensitive to worn bushes and tyres.

MGF ride height: wheel centre to arch lip should be about 35cm. A low car with a stiff ride has probably lost gas.
MGF: ask how often it has been pumped up. Frequent top-ups suggest gas loss; replacement units are now second-hand or reconditioned.
MGF: look for fluid leaks and ask about any coil spring conversion, which changes how the car drives.
TF: pre-2005 cars ride firmly. A very harsh ride may mean optional sports suspension; a softer one, a comfort kit.
Knocks over bumps point to worn bushes or upper ball joints.
Power steering should work, not pull to one side or self-steer. Some owners have disconnected it.
Tyres: different sizes front and rear can be correct, but brands should not be mixed. Cheap tyres spoil the handling.
Brakes: check for pulling and a soft pedal. A TF 160 or Trophy 160 should have its larger front brakes.

Electrics and instruments

Most faults come from age and damp.

Work every switch: lights, indicators, windows, mirrors, heater fan and air conditioning.
Wipers: linkages and motors can fail, so try all speeds.
Headlamps cloud with age and lose brightness, which can affect the MOT.
An intermittent power steering fault needs diagnosis before you buy.
A rattle from the top of the dashboard means broken instrument binnacle mounts, a known fault.
Warning lights, including ABS where fitted, should come on and go out.

Interior, hood and trim

Water leaks are the main enemy.

Damp carpets: most cars leak a little, usually at the front of the doors and down the door trims.
Early cars can leak into the passenger footwell around the heater air intake.
Raise and lower the hood fully. One that sticks partway usually has stretched elastic straps.
Plastic rear windows go cloudy and brittle and can split; 2005 model year TFs have heated glass.
Driver's seat bolster wear, frayed piping and sagging seats.
Check trim matches the version, for example the LE500's leather and equipment.

Paperwork and originality

Versions look alike, and history is the best evidence of care.

Check the VIN on the car against the V5C, and that the engine matches the version claimed.
Confirm a VVC, TF 160, Trophy 160 or automatic from paperwork and specification, not badges.
Look for receipts for head gasket, coolant pipes, radiator, cambelt and water pump, with dates and mileages.
MGF: look for records of Hydragas pumping up, re-gassing or replacement.
Online MOT history helps confirm mileage and shows repeated corrosion advisories.
Note modifications such as coil spring conversions, remaps, exhausts or brake upgrades; they should be declared.

On the test drive

Start from cold if you can and listen for rattles or misfires.
Watch the temperature gauge rise and settle, including in traffic.
On an MGF, feel for a supple ride; a crashy, stiff ride suggests tired Hydragas.
On a TF, expect a firm ride before 2005, but listen for knocks.
Use every gear: the change should be precise with no crunching.
On a VVC or TF 160, use the upper revs once warm; it should pull cleanly.
On a CVT, check smooth take-up and that the manual mode responds.
Steering should be light and consistent and not pull.
Afterwards, look under the car and in the expansion tank for fresh leaks.

Buying at auction

MGFs and TFs appear regularly at UK auctions, including regional sales such as Mathewsons in North Yorkshire. Time with the car is limited, so focus on cooling, suspension and the steel underneath.

What you can check in viewing week

Torch underneath at the subframes, rear sills, front wishbones and underfloor coolant pipes.
Magnet on the sills, arches, side intakes and front wing edges for filler.
VIN and engine details against the V5C and catalogue, especially VVC, Trophy 160 or LE500 claims.
Coolant level and any creamy deposits in the tank or oil filler cap.
On an MGF, ride height at all four corners.
Hood, rear window and carpets for leaks.
Every document, including head gasket, cambelt and Hydragas receipts and old MOTs.
If start-ups are allowed, listen for rattles and watch for smoke or misfires.

What you usually cannot do

You usually cannot drive it, so ride, gearbox, steering and brakes are unknown.
You cannot run it long enough to see whether it holds its temperature.
You usually cannot lift it or remove covers to see the cambelt or inside the sills.

Tips

Read the catalogue critically: a head gasket mention means little without a receipt saying what was fitted and when.
Look for what is not said, such as no cambelt history or no comment on an MGF that sits low.
Remember the buyer's premium and fees on top of the hammer price, and read the terms.
Set your limit beforehand, allowing for a cambelt, tyres or suspension, and stick to it.
Arrange transport home before you bid, and do not drive a car with unknown cooling history far until checked.

What makes one more desirable

Documented cooling system care: improved gasket, metal dowels, stainless pipes and recent cambelt.
Solid subframes and sills with a clean MOT history matter more than shiny paint.
On an MGF, healthy, documented Hydragas, since new units are not made.
The Trophy 160 draws most specialist interest among MGFs; the VVC and TF 160 are preferred for performance.
The LE500 and 85th Anniversary draw interest for limited numbers and specification.
Manuals are generally preferred to CVT automatics.
Low mileage, few owners, matching quality tyres and original specification add confidence.

This guide does not give values or predict prices.

Selling a MG MGF and MG TF

A car with clear history and an honest description stands out, especially on the cooling system.

Preparing the car

Clean underneath; buyers will look at subframes, sills and pipes.
Check the coolant level and that nothing leaks.
Fix small faults such as binnacle mounts, wipers or a sticking hood.
On an MGF, have the Hydragas set to the correct height.
Fit matching quality tyres if the current ones are worn or mixed.

Paperwork

V5C in your name with correct details.
Receipts for head gasket, pipes, radiator, cambelt and water pump, with gasket type where known.
Hydragas records on an MGF.
Service records and old MOTs in date order, plus modification details.

Where to sell

Owners' club classifieds, where buyers know the model.
Specialist MGF and TF dealers.
Auctions such as Mathewsons; check the seller's commission and entry terms first.

Writing the description

State year, version (for example MGF VVC, Trophy 160, TF 135, LE500), gearbox and mileage.
Say whether the head gasket is original or replaced, when, and with what.
Give cambelt history and, on an MGF, Hydragas condition.
Declare modifications, and photograph the subframes, sills, engine bay, hood and interior.

Living with one

Parts supply is good, with many parts shared with other Rover models; MGF Hydragas units are the exception, relying on used and reconditioned stock.
Check the coolant level often; on a K-series a small loss matters.
Do not stretch cambelt intervals; access makes the job more involved than on a front-engined car.
The rear boot is small, so pack light for touring.
None is yet 40 years old, so standard road tax and an annual MOT apply.
Agreed value, limited mileage insurance is available for many examples; declare modifications.

Clubs and registers

Questions people ask

Are MGF and MG TF head gaskets really that bad?

The K-series has a small coolant capacity and long pipes, so coolant loss quickly leads to overheating. The original gasket and plastic dowels were weak points. Many cars now have an improved multi-layer steel gasket, metal dowels and new pipes. Ask for receipts.

What goes wrong with MGF Hydragas suspension?

The nitrogen slowly escapes, leaving the car low and hard-riding. Units can be pumped up and re-gassed, but new units are not made. Wheel centre to arch lip should be about 35cm.

Should I buy an MGF or an MG TF?

The MGF's Hydragas gives a more supple ride but is ageing; the TF has coil springs, sharper steering and a firmer ride, softened for 2005. Condition matters more than model.

Is the VVC worth having?

It revs higher and gives more performance, and the TF 160 uses it too. Listen for a right-hand side rattle, which can mean costly wear in the VVC mechanism.

Should I avoid the Steptronic or Stepspeed automatic?

It is slower and thirstier than the manual and sensitive to the wrong fluid. Look for correct fluid history and a smooth drive.

What is the MG TF LE500?

The first 500 TFs built at Longbridge from 2008, with a 135PS N-series engine, revised head gasket, five-speed manual, leather, air conditioning, hardtop and parking sensors.

Where do MGFs and TFs rust?

Subframes, sills where they meet the rear wings, side intakes, front wing edges and the hollow front wishbones.

Is an MGF or TF a good first classic car?

It can be: parts are easy to find and the clubs help. Buy on history and condition, and have a specialist inspect it if unsure.
