Austin Seven (1922 to 1939)

Why people buy one

• Club, specialist and parts support is excellent, including new uprated crankshafts.
• It is simple to work on, and most jobs can be done at home with basic tools.
• There is a wide choice: early Chummy tourers, saloons, two-seat sports cars, the later Ruby and countless specials.
• The later Ruby (from 1934) is the easiest Seven to live with, with more room and a better ride.
• A large and friendly club scene runs rallies, trials and social runs.

What to weigh up

• Brakes are poor by modern standards, and before 1930 the footbrake worked only the rear wheels while the handbrake worked the fronts.
• Early cars have no synchromesh, a very sharp clutch and low gearing, so driving needs practice and double-declutching.
• Ulsters and other sports models are widely replicated; many are specials built from saloon parts and should be described as such.
• Engines, gearboxes and bodies are often swapped, so a car may not match its claimed year.
• Almost every car has been retrimmed, and wooden body frames can be rotten under sound-looking panels.
• The cars are tiny; check that you fit before bidding. Do not confuse it with the post-war Austin A30, launched in 1951 as the "New Austin Seven", or the 1959 Austin Seven that was an early badge for the Mini.

Where they rust

• The steel chassis side members, especially near spring mountings; rot is usually visible from underneath.
• The rear lower corners of the body.
• Wooden body framing around door openings, door frames and wheelarches.
• Steel saloon shells at the sill line and lower door edges.
• Wings and running boards, which rust but are repairable or replaceable.
• Sliding sunroof channels on saloons, which let water in if the roof does not seal.
• The floor and body mounting points on vans and saloons.

Mechanical weak spots

• Engine: smoke, oil leaks and hard starting mean a rebuild; a rumble from the bottom end can mean a worn crankshaft. Sluggish running may just be ignition timing or a worn carburettor.
• Gearbox: three-speed until 1932, then four-speed with synchromesh added from 1933 on some gears; check it does not jump out of gear.
• Clutch: very sharp on earlier cars with linings fixed directly to the flywheel; the Borg & Beck friction-plate clutch fitted from August 1936 is gentler.
• Steering and front axle: check the steering arm for cracks and the kingpins for wear or seizure.
• Brakes: cable brakes stretch and shoes get oily; Girling rod brakes arrived in 1938 on the last cars.
• Suspension and wheels: check the transverse front leaf spring, rear quarter-elliptic springs, wheel bearings, and for buckled wheels. Check tyre age and type on these narrow wheels.
• Electrics: early cars are basic; many owners add indicators, a third brake light and brighter bulbs.

At a Mathewsons viewing

• Check the chassis number and engine number against the V5C, and ask whether a club has confirmed the car's identity or dated the chassis.
• With a torch, look under the car along both chassis rails, the spring mountings and the front axle and steering arm.
• Press gently around door openings and wheelarches to feel for soft wood in the body frame, and check the doors close cleanly.
• Look at the brake cables or rods for fraying, slack or poor adjustment, and at the brake drums and backplates for oil.
• On a special or a claimed Ulster, ask for the build history and paperwork showing how it is registered; if staff start the car (often by crank handle), listen for knocks and watch for smoke.
