[1] The company's demise may also have been due to the development cost of a completely new coupé model with a rear-mounted Hillman Imp engine, the prototype of which was incomplete.

From the late 1940s, Jack Turner built a series of one-off specials, and prepared racing cars, including building his own engines.

The first cars for sale were based on one of the specials, and consisted of chassis, independent suspension units using transverse leaf springs, and Turner's own alloy wheels.

[1] In 1956, the uprated 948 cc unit from the Austin A35 was adopted, and the model renamed Turner 950 Sports, but, apart from fully hydraulic brakes with optional front discs, was otherwise unchanged.

[3] In 1959, the Turner Sports Mk I was introduced, and although similar to the outgoing model, featured substantial revisions to the body and chassis, and front disc brakes became an option.

[3] In 1960, a Turner Sports Mk II model appeared, with improved interior trim and further minor styling revisions.

[4] In late 1963, the final model was introduced as the Turner Sports Mk III, and featured a tuned version of the Ford 1,500 cc engine as standard.
