Caterham Seven 420R

The 420R is the sharper, road-and-track-minded end of the Caterham Seven range, pairing the 2.0-litre Ford Duratec four-cylinder with the R Pack. That adds sport suspension, a limited-slip differential, a lightweight flywheel, a rear anti-roll bar, composite race seats and a carbon fibre dashboard. The page quotes 210 bhp and a 0-60mph time of 3.8 seconds.

This is the dealer's own demonstrator, finished in Gulf Blue with a Ballistic Orange nose band and bonnet stripe over a black interior. Options include front ventilated discs with quad-piston calipers, 13-inch black Apollo alloys, a lowered floor, a quick-release MOMO leather wheel and a heater. A full windscreen, hood and sidescreens are also fitted. No mileage or registration is given on the page.
