Built from a 1973 road car, this Mini has been thoughtfully developed into a high-performance fast road example, offering lively performance and excellent usability.

While the car has benefitted from competition-inspired engineering during its life, its current set-up is focused on reliability, drivability and enjoyment rather than outright motorsport use.

An earlier supercharged engine was removed in favour of a naturally aspirated unit better suited to sustained road driving, resulting in a responsive and engaging Mini that remains easy to live with while offering performance well beyond standard specification.
The interior is fitted with supportive road bucket seats, that provide a secure driving position without compromising comfort on longer journeys.

A full roll cage is installed, offering additional structural rigidity and reassurance, but it does not dominate the cabin and could be removed if a future owner wished to return the car to a more traditional road-focused layout.
