GTM Cars Ltd was a UK kit car maker based in Kingswinford. It started in 1967 when Bernard Cox and Jack Hosker created the Cox GTM, a mid‑engined car using Mini parts. Production began in a garage and, by autumn 1968, Cox stopped after about 50 kits. Howard Heerey and his father took over and renamed the car GTM. By 1971 around 170 kits had been made, but in 1972 a road widening forced the company to close. A Hartlepool fiberglass firm bought the demonstrator car and molds but never produced cars. The project was bought by KMB Autosports in 1976, who made spares but no new kits.

In 1980 GTM was bought by Peter Beck, Paddy Fitch and Dougal Cowper and moved to Sutton Bonington in 1982. Over the next two decades, GTM refined the GTM Coupé and developed new models, including the Rossa and Mk2. The Rover K‑series engine was fitted to the third‑generation Rossa, called the K3, making it one of the first mid‑mounted K‑series GTMs.

In 1998, after years of development, the Libra was launched as a more up‑market model. Four years later came the Spyder, a softer‑styled convertible sharing some design cues with the Libra. In 2003 GTM Cars was bought by RDM Group and moved to Coventry in 2004. Under RDM, two new projects—the Ballista and the 40TR track car—were developed, but neither progressed beyond development. GTM continued selling Libra and Spyder kits or fully built cars.

In December 2007 GTM Cars Ltd came under Potenza Sports Cars, owners of Westfield Sportscars. In January 2008 GTM showed a redeveloped 40TR at Autosport, though 40TR work was paused to focus on Ballista. At the Stoneleigh kit car show in May 2009 a red Spyder was displayed; it was sold as an ex‑demonstrator, and Westfield said GTM would be rebranded as Westfield GTM rather than a standalone marque.

In January 2010 Westfield announced it would discontinue the current GTM models due to parts supply issues and would design and manufacture a new GTM over the following year. After years of stagnation, the brand entered administration on June 9, 2022, and liquidation began on December 18, 2023. The brand ended and its assets were dispersed to various buyers in the kit‑car sector.
