History

A total of around 60 Madison Roadsters were manufactured by the British company GP (Grand Performance). 

These vehicles were predominantly kit cars based on the chassis of the Volkswagen Beetle and designed as retro roadsters in the style of the 1930s. The GP Madison was particularly popular in the 1970s and 1980s and was offered as a modular system, allowing owners to assemble most of the vehicle themselves.

An even more exclusive series exists from this already limited edition: only about 14 examples were manufactured with Ford components, making them a true rarity among collectors. Particularly sought-after are the models with the Ford Cortina powertrain, which were based on a specially developed ladder frame. Models with Ford Pinto engines are even rarer, as these were manufactured exclusively as left-hand drive vehicles for the US market.

A larger body had to be developed specifically for the Ford-based roadster in order to integrate the powerful technology – an adaptation that gave the vehicle even more harmonious proportions.

The exact ratio of Cortina and Pinto variants is not documented. 

In later years, some of these roadsters were modified with more powerful Ford Sierra engines, at the expense of their originality.

The very small number of units produced makes the original Cortina and Pinto roadsters rare collector's items.
