Caterham Seven Supersport 140

This 2013 Caterham Seven is built around the idea of doing without. It is unpainted, with a bare aluminium finish, has no heater, and uses carbon fibre for the nosecone, cycle wings and rear arches to keep weight down.

It began life as a standard Sigma 125 and has been upgraded to full Supersport specification. That means 140 bhp from the 1.6-litre Ford Sigma, a lightweight clutch and flywheel, a limited-slip differential and a five-speed Type 9 gearbox. Adjustable Meteor Motorsports CORE ONE dampers, grooved front discs and a lithium battery add to the driver-focused set-up.

It has covered 15,300 miles. Inside are composite Tillett seats, a carbon dashboard, a Momo-style Motolita wheel and push-button start, with Toyo R888R tyres on the front and Nankang NS2R on the rear. The dealer says it has been inspected, serviced and MOT'd.
