The car used a tuned version of the push rod, overhead valve four cylinderMorris TPBG type engine that was also fitted to theWolesley 12/48 and Morris 12. The MG version had twin SU carburettors and developed 54 bhp (40 kW) at 4500 rpm. Drive was to the live rear axle via a four speed manual gearbox with synchromesh on the top three ratios though on some early cars it was only on the top two speeds. Nineteen inch wire wheels were fitted and the 10-inch (250 mm) drum brakes were hydraulically operated using a Lockheed system. In-built hydraulic jacks were standard. Suspension was by half elliptic springs all round with a live rear axle and beam front axle. Luvax shock absorbers were fitted, the rear ones adjustable from the dashboard

The bodies were made in-house by Morris and had the traditional MG grille flanked by two large chromium plated headlights. Unlike the SA the front doors did not have separate quarter light windows. The spare wheel was carried on the left front wing with a second spare on the other side as an option. Inside there were individual seats in front and a bench seat at the rear, all with leather covering. A fitted radio was an option.

A special version of the car was made for police use and had a 1707 cc engine and calibrated speedometer.

The British "Motor" magazine tested a VA tourer which reached a top speed of just over 76 mph (122 km/h) and a 0-50 mph time of 15.8 seconds. With the windscreen folded down the top speed increased to nearly 82 mph (132 km/h).

The factory could also supply the car as a Tickford drophead coupé or as a four door tourer. The saloon was priced at around £325, the four seat tourer £280 and the Tickford coupé £351 all prices depending on exact specification. 564 tourers and 591 coupés were made. A very few chassis, probably only two, went to external coachbuilders.

Production stopped with the outbreak of World War II in 1939. After the war, MG launched the Y-Type to fill the small saloon slot.
