Overview

The Gardner Douglas GD427 is generally regarded as one of the finest sixties sports car evocations built in Britain. Designed around a steel triangulated tubular backbone chassis with a GRP semi-monocoque tub, it delivers a stiff, rattle-free structure and a low centre of gravity that translates into sharp, neutral handling. Independent double-wishbone suspension, adjustable coil-over dampers and a limited-slip differential make the GD a genuine driver's car, equally happy on a B-road blast or a European touring trip. Add a big-cube American V8 and the result is an analogue driving experience with real theatre.

This bright-red example pairs that celebrated chassis with a 350ci (5.7-litre) short-block Chevrolet V8, fitted with an Edelbrock single-plane inlet manifold, sports cam and tubular stainless-steel headers. Drive goes through a Tremec TKO five-speed manual, and there's a big-V8 soundtrack to match courtesy of a chromed underslung twin stainless exhaust exiting centrally at the rear. The vendor tells us it starts easily, pulls strongly through all gears and sounds fantastic.

Inside, the cabin is trimmed in cream leather with red piping and Gardner Douglas-embroidered headrests, complemented by black carpets and Willans four-point harnesses. A full set of classic Smiths gauges faces the driver, mounted behind a 14-inch wood-rim Mota-Lita steering wheel. Outside, the deep gloss red paint presents excellently, and the car sits on 17-inch faux-Halibrand alloys with aluminium spinners and good-tread Falken FK452 tyres. Chrome quarter-bumper overriders, twin roll-over hoops with cream head fairings and the iconic 427 wing badge complete the look.

It's a beautifully sorted example that suits the enthusiast who wants the raw V8 sports car experience with genuine handling pedigree and none of the compromises.
