Caterham R500 SV

This Caterham started out in 2021 as a 620S on the wider SV chassis. In 2023 it was converted to R500 specification, so it is a one-off rather than a factory-built R500.

The conversion centres on a bespoke Dave Hersey-built 2.0-litre Duratec with steel conrods, forged pistons, race bearings, a keyed crankshaft and a dry-sump oil system. It produces 267 bhp and drives through a five-speed manual gearbox with a limited-slip differential and lightweight flywheel. Other fittings include carbon wings and airbox, vented front discs with four-piston calipers, and Toyo R888R tyres on black 13-inch alloys.

It is finished in Caterham's F1 green and yellow livery and has covered 10,400 miles. The dealer lists a fresh service, 12 months' MOT and its own warranty.
