Turner Sports Cars Ltd. produced lightweight sports cars from late 1954 to early 1966. Before that, company founder John (Jack) Henry Turner had been an enthusiastic racer. He'd already built a diverse assortment of one-off racecars and even a couple small engines of his own design. In a 1949 advertisement, Turner advertised "castings in light alloy" and "manifolds made to blueprint". Jack Turner's first racecar was a supercharged MG Magnette that he converted into an aluminum-bodied "special" and entered in hillclimb competitions. As a confirmed MG enthusiast, Jack Turner comprehended the niche that opened when MG discontinued their TD model. Building custom racecars hadn't provided a comfortable lifestyle, so he turned his considerable entrepreneurial energy to developing an economical sports car based on the Austin A30. Turner Sports Cars featured notably rigid frames constructed of large diameter steel tubes. (A fiberglass monocoque GT model was the exception that proved the rule, but only nine Turner GT's were built.) Turner front suspensions featured dual wishbones and coil springs. Torsion spring rear suspension was standard equipment, but helical springs were later offered as an option. Most Turner sports cars came with fiberglass exterior bodywork, although the first prototype had an aluminum body and some Turners are known to have been constructed with steel bodies of similar appearance.
