The Marlin Roadster was a kit car produced between 1979 and 1993.

The Roadster was a well engineered 2-seat sports car in the style of 1930s sports car with a modern edge. The Roadster was the first car to be given the Marlin badge in 1979.  

Paul Moorhouse was the designer and he based the Roadster on Triumph mechanicals that came from the Triumph Herald/Vitesse/Spitfire/GT6 but designed and built its own chassis rather than using the Triumph's. 1983 saw the move to the Marina as the donor car of choice due to dwindling supplies of Triumph donors. 

The Marlin trade mark was the clever use of the windscreen frame the roll over bar. The body tub was made from aluminium with the use of GRP for the more complex panels. Power varied from the Triumph and Marina donor engines to the Rover V8.

The Roadster project was sold to Yorkshire Kit Cars in 1993 along with the Berlinetta.
