The Classic Car Owner's Guide
1930s cars: what Britain built and drove between the wars
In the 1930s, small saloons from Austin, Morris, Ford and Hillman were built in huge numbers for British buyers. New laws brought the Highway Code, the driving test and the 30 mph limit in built-up areas. This guide covers the cars that mattered and what to know before owning one today.
Motoring in Britain in the 1930s
When the first Highway Code was published in 1931, Great Britain had about 2.3 million motor vehicles, and around 7,000 people were dying on the roads each year. Small family cars from Austin, Morris and Ford were built in their hundreds of thousands.
The rules of the road changed quickly. The Road Traffic Act 1930 scrapped the widely ignored 20 mph limit for cars. Four years later, the Road Traffic Act 1934 brought back a 30 mph limit in built-up areas and required new drivers to pass a test. Belisha beacons appeared at pedestrian crossings in 1934, and the compulsory driving test began in 1935.
The industry changed just as fast. Ford opened its Dagenham plant in 1931, and the Rootes family brought Humber and Hillman under one roof. Morris designed its Eight as a direct rival to Ford's Dagenham-built Model Y, and Vauxhall introduced the first British car of monocoque construction in 1937.
The decade ended with war. Austin Seven production stopped in 1939, and Vauxhall's Luton factory halted car production for the war effort.
Cars that defined the 1930s
Austin Seven
1922 to 1939 | Austin, Britain
The car that put Britain on wheels was still on sale throughout the decade. Its 747cc four-cylinder engine powered around 290,000 cars and vans by the time production ended in 1939.
Ford Model Y
1932 to 1937 | Ford, Britain
Built mainly at Dagenham from 1932, the 933cc Model Y gave Ford a small car for British and European buyers. More than 100,000 were made at Dagenham before production ended in 1937.
Morris Eight (Series I)
1935 to 1937 | Morris, Britain
Morris's answer to the Ford Model Y used a 918cc side-valve engine closely based on Ford's eight horsepower unit. The Series II replaced it in 1937. Around 164,100 were built, and it became one of the great Morris successes of the decade.
Austin Ten
1932 to 1947 | Austin, Britain
Slotted between the Seven and the larger Twelve, the Ten was Austin's best-selling car of the 1930s. It stayed in production until 1947.
Hillman Minx
Introduced 1932, pre-war design built into the late 1940s | Hillman (Rootes), Britain
The 1,185cc Minx arrived as Hillman came under Rootes control and gained synchromesh gears by the middle of the decade. The same basic design, refreshed over the years, carried on after the war.
Vauxhall Ten-Four (H-type)
1937 to 1940 | Vauxhall, Britain
The first British car built with integral, or monocoque, construction, it also had hydraulic brakes and independent front suspension. More than 42,000 reached British owners before war stopped production in 1940.
MG TA Midget
1936 to 1939 | MG, Britain
The first of the T-series swapped the old overhead-camshaft engine for a 1,292cc pushrod unit derived from the Morris Ten. Purists objected, but 3,003 were built.
SS Jaguar 100
1935 until the Second World War | SS Cars, Britain
The car that introduced the Jaguar name in September 1935, it used a Weslake-designed overhead-valve head. About 309 were built, with a 3.5-litre version joining the 2.5-litre car for 1938.
Morgan 4/4
From 1936 | Morgan, Britain
Morgan's first four-wheeler arrived in 1936 with a Coventry Climax engine. By 1939 a Standard overhead-valve engine was also offered.
Citroen Traction Avant
1934 to 1957 | Citroen, France (also built in Slough)
One of the first mass-produced cars with front-wheel drive, it also had a monocoque body with no separate chassis. British buyers could buy versions assembled at Citroen's Slough factory.

Owning a 1930s car today
- Learn the gearbox. Older gearboxes may have weak synchromesh or none at all, and cars without it need double declutching, as early Austin Sevens do.
- Use the right fuel. The Federation of British Historic Vehicle Clubs (fbhvc.co.uk) advises Super E5 petrol for older cars, and ethanol-sensitive seals and hoses should be replaced with compatible parts.
- Tax and MOT. Cars over 40 years old can join the historic vehicle tax class and are generally exempt from the MOT, unless substantially changed.
- Roadworthiness is still the owner's job. MOT exemption does not remove the legal duty to keep the car roadworthy at all times.
- Join a club. The Vintage Sports-Car Club (vscc.co.uk), founded in 1934, caters for pre-war cars including selected post-vintage models built up to 1940. Austin Seven owners have the Austin Seven Clubs' Association (a7ca.org), which can help identify a car and links owners with local clubs.
