The TVR Grantura is the first model in a long line of TVR cars and debuted in 1958. The cars went through a series of developments leading to the I to IV and 1800S models. The last ones were made in 1967.

These coupés were hand-built at the TVR factory in Blackpool, England with varying mechanical specifications and could be had in kit form. All cars featured a cocktail of Austin-Healey brakes, VW Beetle or Triumph suspension parts and BMC rear axles.

The Grantura bodyshell was made from glass-reinforced plastic and made use of a variety of proprietary components. The bonnet was front hinged. There was no opening at the rear but the boot could be accessed from inside the car - the spare wheel had to be removed through the front doors. Buyers could choose from a range of powerplants which included a choice of side or overhead valve engines from Ford, a Coventry Climax unit or the MGA B-series engine.
