Caterham Seven Supersport 140

This Caterham began life as an Academy car, the one-make series that introduces many drivers to Sevens, and has since been upgraded to SuperSport specification. The 1.6-litre Sigma engine now makes 140 bhp and drives the rear wheels through a five-speed gearbox, on the S3 chassis.

The chassis changes are substantial: wide-track front suspension, a limited-slip differential, an uprated master cylinder, four-piston front calipers with vented discs, and a de Dion rear axle. A lightweight flywheel and clutch, track roll cage, side impact bar, race harnesses and composite seats show its circuit intent, while a heater, heated windscreen and full weather gear keep it usable on the road.

First registered in 2010, it has covered 12,500 miles and has had two owners from new. It is finished in a green and yellow livery inspired by Caterham's Formula 1 team, and is offered with a fresh service, 12 months' MOT and the dealer's own warranty.
