Austin A30 and A35 buyer's guide
The Austin A30 was Austin's small family car of the early 1950s, launched at the 1951 Earls Court Motor Show as the new Austin Seven and built at Longbridge from 1952. In 1956 it became the A35, with a bigger engine and a better gearchange. The saloons ended in 1959, the Countryman estate in 1962, and the vans carried on until early 1968, so the family covers well over a decade and a half and a surprising range of bodies: two and four-door saloons, the Countryman, vans and a short-lived pick-up.
People buy them because they are small, simple and cheerful to drive, with the A-series engine that went on to power the Mini, Morris Minor and many other BMC cars. Mechanical parts are well supported, there is a dedicated owners' club, and the A35 has a following in historic racing at events such as the Goodwood Revival. Against that, the bodies are unitary steel shells that rust, and many cars have had decades of patching, engine swaps and conversions.
This guide is for buyers looking at an A30 or A35 at a dealer, privately or at an auction such as Mathewsons in North Yorkshire, and for owners getting ready to sell. It covers what to check, not how to repair: a specialist or the owners' club can advise on work.

The Austin A30 and A35 in brief
Austin needed a modern small car to take on the Morris Minor, and the A30 was its answer. It was Austin's first unitary construction car and introduced the overhead-valve A-series engine in 803cc form. For a buyer, the unitary body is the key fact: the sills, floor and spring hangers carry the loads, so rust there is structural rather than cosmetic.
The earliest A30s, coded AS3 by the owners' club, have a round central speedometer, the fuel filler on the rear wing and a single rear light. From late 1953 came a larger grille, a new dashboard with a trapezoidal speedometer and a two-door saloon. The two-door became the more common car, which is why four-door saloons, especially A35s, are seen less often today.
In 1954 Austin added a 5cwt van and the Countryman estate, sharing the same rear body but with the Countryman trimmed and seated as a passenger car. Because commercial vehicles avoided purchase tax, many vans were later given side windows and rear seats, and these conversions are far more common than factory Countrymen.
The A35 arrived in 1956 with a 948cc engine of about 34bhp, a remote gearchange and revised ratios. It is easy to spot: the grille is painted body colour inside a chrome surround, the rear window is much larger and wraps around, and saloons gained flashing indicators in place of semaphore trafficators. A saloon-based pick-up was added in 1956 and dropped in 1957 after fewer than 500 had been built. The A35 saloon ended in 1959, when the Mini and the A40 Farina took over its place in the range.
The commercial range ran on. The Countryman was dropped in 1962, the year the van gained smooth doors. From late 1962 the van had a 1098cc engine, and from late 1963 a Mini-type 848cc engine was offered too. The 1098cc option went in 1966, and the last vans left Longbridge in February 1968. Van engines were low compression versions with less power than the saloon equivalents.
Today many cars have been modified, from an A35 engine in an A30 or front disc brakes to full race builds with 1275cc engines. Neither is wrong, but originality and identity matter a great deal on the rarer versions.
Versions to know
| Version | Years | What to know |
|---|---|---|
| A30 four-door saloon, early (AS3) | 1952 to 1953 | The first production cars, with a round central speedometer, fuel filler on the rear wing, single rear light and small grille. Uncommon; check early fittings have not been swapped for later ones. |
| A30 two-door and four-door saloon | Late 1953 to 1956 | Larger grille, new dashboard and the two-door option. 803cc engine, long floor gear lever and semaphore trafficators. Many now have a 948cc or larger engine because 803cc parts are scarcer. |
| A30 van and Countryman | 1954 to 1956 | 5cwt van and passenger Countryman sharing the same rear body, with low compression 803cc engines. The van has a roof ventilator; a factory Countryman does not, and has full-length headlining and rear seats from new. |
| A35 two-door and four-door saloon | 1956 to 1959 | 948cc engine, remote gearchange, painted grille with chrome surround, larger wrap-around rear window and flashing indicators. The two-door is the most common A35; the four-door was built in far smaller numbers. |
| A35 pick-up | 1956 to 1957 | Saloon-based 5cwt pick-up built only briefly. Fewer than 500 were made, and the owners' club's verified records count 478. Many panels and trim items are unique to it, so check identity and completeness. |
| A35 van and Countryman | 1956 to 1962 | 948cc engine in low compression form and the A35's remote change. The Countryman ended in 1962, when the van was revised with smooth doors. Converted vans with cut-in side windows are common and should not be described as Countrymen. |
| A35 van, 1098cc | Late 1962 to 1966 | The most powerful factory version. 1098cc engines have also been fitted to many earlier cars, so look for evidence the van is what it claims to be. |
| A35 van, 848cc | Late 1963 to 1968 | Mini-type 848cc engine with a lower axle ratio. Built until February 1968, these are the last of the line. |
| Modified and race cars | Any | Cars with 1275cc engines, front discs, uprated suspension or full race preparation. Ask for build records and, for race cars, logbooks. |

Myths and realities
Any A35 estate with side windows is a Countryman.
Many vans were converted after purchase to avoid purchase tax, by cutting in side windows and adding a seat. A factory Countryman has no roof ventilator, full-length headlining and rear seats from new, and the owners' club can help check the chassis number.
An A30 is just an A35 with a smaller engine.
The A30 has a different grille, a smaller rear window, a long floor gear lever, semaphore trafficators and its own engine and gearbox parts. Some A30 parts are much harder to find, so confirm the car is the model you want.
Drum brakes on these cars are dangerous.
The standard brakes are adequate for a standard engine when properly adjusted and in good order. Poor adjustment and seized wheel cylinders are the usual cause of bad brakes, not the design.
A bigger engine always makes the car more desirable.
A 948cc engine in an A30 is a common, accepted upgrade, but on early A30s, pick-ups and vans the original engine type matters to buyers. Declare any swap and keep the old unit if you have it.
What to check
Bodywork and structure
The body is the chassis, so most of your time should go here. Take a torch, a magnet and a mat to lie on, and ask before you probe anything.
- Rear spring hangers and the metal around them: the classic weak spot, with rust spreading into the boot floor and inner rear wings. Look for neat seams rather than heavy plating or filler.
- Outer and inner sills along their full length, including where they meet the front wings and the rear wheel arches.
- The offside (driver's side) inner sill, which carries the handbrake lever mounting; rust here can leave the lever poorly supported.
- Floor pans, jacking points and the front and rear chassis legs, from underneath and inside the footwells under the carpets.
- The front panel below the grille, the front valance and the radiator support, all of which rot and are often patched.
- Front wings at the rear lower corner, headlamp bowls, bonnet edge and, on A35s, around the indicator mounting. The bolt-on wings can hide rot in the sill ends and hinge area.
- Boot floor, spare wheel well, inner rear wings, the area around the rear lights and the bottom of the boot lid.
- Door pillars and hinges: a dropped door can be worn hinges or rot in the pillar. Check all door bottoms, especially the rear doors on four-door cars, and the rear doors on vans and estates.
Engine
The A-series is simple and robust when maintained, but find out which engine is fitted before judging it. Many cars no longer have their original unit.
- Identify the engine: 803cc on an A30, 948cc on an A35, 1098cc or 848cc on later vans. Larger units such as the 1275cc are common and should be declared.
- Blue smoke on start-up suggests worn valve stems or seals; smoke under load points to worn bores and rings.
- A deep rumble or knock from the bottom end means worn crankshaft bearings and a rebuild. A rattle at the front is often the timing chain, which is common and less serious.
- Check for coolant in the oil and oil in the coolant, which can mean head gasket failure, often at the rear of the engine.
- Oil leaks are common, most often from the rear crankshaft seal, rocker cover, timing cover and tappet covers. Light seepage is normal; heavy loss is not.
- Ask whether the cylinder head has been converted for unleaded fuel. An original head can suffer valve seat wear if driven hard.
- Zenith carburettors were fitted from the factory, and many cars now run an SU. Either is fine, but check for flat spots and a steady idle.
Gearbox and drivetrain
The four-speed gearbox is generally reliable but has no synchromesh on first or reverse, and there are two main casing types.
- Listen for bearing noise in neutral that stops when the clutch is pressed, and for whine in the gears.
- Check for weak synchromesh, especially on second, and for the gearbox jumping out of gear on acceleration or over-run.
- Look at the gearbox casing: the later ribbed casing is stronger than the smooth casing, and a car with a larger engine should have the ribbed type or a box built with stronger internals.
- A30s have a long floor lever, A35s a short remote change. An A30 with a remote change has had a gearbox swap.
- Rear axle: oil leaks are common, and whine that rises with speed points to wear. Overfilling the axle can let oil reach the rear brake shoes.
Suspension, steering and brakes
The running gear is simple and well supported, but it needs regular greasing and adjustment. Neglect here usually says something about the rest of the car.
- Kingpins and the lower suspension pivots need grease at regular intervals. Look for fresh grease at the nipples and rock each front wheel top to bottom for play.
- Steering is by a steering box with an idler, not rack and pinion. Check for excessive free play at the wheel and wear in the box, idler and track rod joints.
- Rear leaf springs can sag, crack or wear at the leaf ends; the car should sit level. Check the spring hangers again from this angle.
- Brakes are 7in drums, hydraulic at the front and mechanical at the rear. The pedal should be firm and the car should stop straight.
- The master cylinder is under the floor on the driver's side, exposed to water and salt. Look for leaks and corrosion there and at each wheel cylinder.
- Common brake upgrades are larger A40 front drums, MG Midget front discs and a servo. These are acceptable if well done, but ask who fitted them.
Electrics and instruments
The 12-volt electrics are simple, so most faults come down to earths, connectors and old wiring rather than failed parts.
- Work every light, the horn, wiper and heater fan, and the trafficators or flashing indicators depending on the model.
- Semaphore trafficators on A30s and earlier commercials should rise and fall cleanly; sticking arms are common.
- Look for corroded bullet connectors, brittle insulation and amateur accessory wiring behind the dashboard and in the engine bay.
- Check whether the car is positive or negative earth, and whether it has a dynamo or an alternator conversion. This matters for radios, electronic ignition and battery chargers.
- Make sure the speedometer, fuel gauge and any temperature or oil pressure instruments work, and that the ignition warning light goes out once the engine is running.
Interior and trim
Original, unworn interiors are rare and many cars have been retrimmed. Correct trim matters most on early A30s and the commercial versions.
- Check seats for splits, collapsed springs and sagging frames, and whether the covers suit the car's year and model.
- Headlining: look for stains and sagging. On a van, headlining at the front only is correct; full-length headlining is a Countryman feature.
- Damp carpets or rusty seat frames point to leaks from the screen, quarter lights, door seals or rear doors.
- Chrome bumpers, over-riders, grille surround and badges: original items pit, and correct grille badges are scarce.
- On a Countryman, check for side trim panels, rear door cards and a factory-type rear seat. On a pick-up, check for the correct load area covers and trim.
Paperwork and originality
With so many conversions, swaps and race builds, the paperwork is as important as the metal, especially on the rarer versions.
- Match the chassis number on the car to the V5C, and check the model prefix suits the body: saloon, van, Countryman and pick-up codes all differ.
- For a Countryman or pick-up, ask the owners' club to help confirm the chassis number and identity before you commit.
- Check the engine number and ask whether the engine is original to the car. Many A30s now have 948cc or larger units.
- Look for receipts and photographs of structural work, particularly sills, floors and spring hangers.
- Ask the owners' club or the British Motor Museum at Gaydon whether factory records survive for the car.
On the test drive
- Start from cold if you can, and watch for blue smoke and listen for knocks as the engine warms.
- Change gear through all four ratios, including down into second, to test the synchromesh, and remember first has none.
- Accelerate and lift off in second and third to see if the gearbox jumps out of gear.
- Feel the steering for heaviness, wander or vague straight-ahead, which points to wear in the box, kingpins or joints.
- Brake firmly on a clear, straight road. The car should stop straight with a firm pedal, though more effort is needed than in a modern car.
- Try the handbrake on a slope; it should hold the car when the rear brakes are properly adjusted.
Buying at auction
A30s and A35s appear regularly at UK classic auctions, including regional sales such as Mathewsons in North Yorkshire. 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 rear spring hangers, sills, floor, jacking points and front panel, ideally lying on a mat.
- Use a magnet on the sills, lower wings, wheel arches, door bottoms and the panel below the grille for filler.
- Check the chassis number and prefix against the V5C and the catalogue, and look at the engine number.
- On an estate, look up at the roof for a ventilator and inside for full-length headlining and factory side trim.
- Lift the bonnet and check the oil and coolant for contamination, and look for leaks and amateur wiring.
- Read the history file, including old MOTs and any club or Heritage Certificate paperwork.
What you usually cannot do
- You usually cannot drive the car, so the gearbox, steering, brakes and clutch remain unknown.
- You usually cannot put the car on a lift, so a full underside check is not possible.
- You cannot remove trim or panels to see inside sills, door pillars or behind the bolt-on front wings.
- You often cannot run the engine long enough to judge it when hot.
Tips
- Read the catalogue critically. Words such as restored, solid or recommissioned mean little without receipts and dates, and note what is not mentioned.
- Treat any claim of a genuine Countryman, pick-up or early A30 as something the paperwork must prove.
- Remember the buyer's premium and any other fees are added to the hammer price, and read the terms before bidding.
- Set your limit before the sale, including likely work, and stick to it.
- Arrange transport home before you bid. Do not assume a car you have not driven is roadworthy, and sort insurance before any journey on the road.
What makes one more desirable
- Structural condition comes first. A car with documented sill, floor and spring hanger work is easier to sell than a freshly painted one with no evidence.
- Rarer versions draw the most interest: the A35 pick-up, factory Countryman estates, four-door A35 saloons and early A30s with their first fittings.
- A genuine Countryman is more sought after than a converted van, and an unconverted van in original commercial form is increasingly scarce.
- Original engine type matters most on rarer versions; on everyday saloons a 948cc engine in an A30 is widely accepted.
- A long ownership history, old MOTs and receipts, especially for regular greasing and brake work, reassure buyers.

Selling a Austin A30 and A35
Buyers know to look underneath and to question estates and engine swaps, so an honestly described car sells more easily.
Preparing the car
- Clean the underside as well as the paint, as buyers will look at the spring hangers, sills and floor.
- Have the brakes adjusted and checked, as poorly adjusted brakes put people off on a test drive.
- Grease the suspension and steering points and have the car serviced so it starts, idles and drives well.
- Fix small faults such as non-working lights, trafficators or gauges.
Paperwork
- V5C in your name with the correct chassis and engine details.
- Receipts and photographs for structural work and major mechanical work.
- Any Heritage Certificate or owners' club confirmation of identity, especially for a Countryman or pick-up.
- Details of modifications, who did them and when, and any original parts that go with the car.
Where to sell
- The Austin A30-A35 Owners Club, where buyers know the model.
- Specialist classic dealers who handle small British saloons.
- Classic car auctions, including regional sales such as Mathewsons; check the seller's commission and entry terms first.
Writing the description
- State the model and year, body style, engine size and whether it is original, and the gearbox type.
- Say clearly whether an estate is a factory Countryman or a converted van.
- Be honest about structural work: what was done, when and by whom.
- Photograph the underside, spring hangers, sills, boot floor and engine bay as well as the outside and interior.
Living with one
- Mechanical parts for the 948cc and later A-series engines, brakes and suspension are widely available and many are remanufactured. Some 803cc engine parts, A30 trim and commercial-specific items are harder to find.
- The owners' club runs a spares service and publishes technical advice, which is valuable for the less common parts.
- Regular greasing of the front suspension and steering, and frequent brake adjustment, are part of normal ownership.
- Cars are small and noisy at speed but cope with A and B road traffic.
- Classic insurance with an agreed value and limited mileage is widely available; declare modifications, particularly engine and brake changes.
Clubs and registers
Questions people ask
What is the difference between an Austin A30 and an A35?
The A30 (1951 to 1956) has an 803cc engine, a chrome grille, a small rear window, a long floor gear lever and semaphore trafficators. The A35 (1956 onwards) has a 948cc engine, a painted grille with a chrome surround, a larger wrap-around rear window, a remote gearchange and, on saloons, flashing indicators.
Where do Austin A30s and A35s rust?
Mainly the rear spring hangers and the boot floor and inner wings around them, the inner and outer sills, the floors and jacking points, the front panel below the grille and the radiator support, the front wings, door pillars and door bottoms.
How can I tell a genuine Countryman from a converted van?
A factory Countryman has no roof ventilator, full-length headlining, side trim panels and rear seats from new. Many vans were converted with cut-in side windows. The owners' club can help check the chassis number and identity.
Which version should I buy?
For most people, an A35 two-door saloon is the easiest to own, with the stronger 948cc engine and better gearchange. Body condition matters more than the model.
Is an Austin A35 a good first classic car?
It can be. It is simple, economical and well supported by its club, and mechanical parts are easy to find. The body needs careful inspection, so have an expert look underneath if you are unsure.
How many A35 pick-ups were made?
Fewer than 500. Figures of about 475 are often quoted, and the owners' club's verified records put it at 478, which makes it the rarest regular production body.
