The TVR M series was built between 1972 and 1979. The series replaced the outgoing TVR Vixen and Tuscan models, and is characterized by a common chassis and shared body style. As with other TVR models before and since, the M-series cars use a front mid-engine, rear-wheel drive layout and body-on-frame construction. The bodies themselves were built from glass-reinforced plastic (GRP).
The M series was regarded by contemporary reviewers as being loud and fast and having excellent road holding. This came at the expense of unusual ergonomics, and heating and ventilation systems that were sometimes problematic.
The series includes the 1600M, 2500M, 3000M, 3000S, and Taimar, as well as turbocharged versions of the 3000M, 3000S, and Taimar. The first model to start production was the 2500M in March 1972, after being built as a prototype in 1971. A small number of 5.0 L Ford V8-powered cars were finished or converted by the TVR North America importer; these were sold as the 5000M. A total of 2,465 M-series cars were built over the nine years of production. Because of the hand-built and low-volume nature of TVR production, there are many small and often-undocumented variations between cars of the same model that arise due to component availability and minor changes in the build process.
