The 420 Cup is Caterham's track-focused Seven in its most club-racing-ready road-legal form. It pairs the naturally aspirated 2.0-litre Duratec, here making 210 bhp, with a six-speed sequential gearbox, limited-slip differential and dry-sump lubrication, all in a car that weighs little more than a feather.
This 2021 example is finished in Exocet Red with a white-painted roll cage, carbon aero screen and a carbon-finish 620-style dashboard. It rides on Bilstein race dampers with ten stiffness settings, 13-inch Apollo wheels with Avon ZZS tyres, uprated ventilated brakes and a quick-ratio steering rack. Inside are heated carbon-fibre seats, Schroth six-point harnesses and a suede MOMO wheel.
It has covered 4,188 miles and is registered HT21OKW. The dealer describes it as well maintained.
