The Roadster was the original car and was based around Triumph Herald range components. (
e.g Spitfire,Herald,Vitesse,GT6) The two seat body built of aluminium and glass fibre had a radiator grille slightly similar to pre-war Alfa Romeo sports cars.
As standard, any of the 4 or 6 cylinder engines of the time could be fitted (1147-2498cc), along with overdrive or non-overdrive gearboxes.
 In 1981 the Morris Marina became the donor car replacing the Triumph and the Marina engine became standard although many customers fitted engines, gearboxes and back axles of their own choice.
Fitted with the two-litre inline-six from a late Triumph Vitesse, a top speed of 177 km/h (110 mph) was achievable.
