Bristol 405 Roadster Special

This is a one-off special built on a 1958 Bristol 405 and finished as an open roadster, rather than the factory saloon or the rare Zagato-bodied and drophead variants. It is painted silver.

The big change is under the bonnet, where the engine has been supercharged using a Mercedes-Benz Kompressor unit. It also gets a tubular, gas-flowed exhaust manifold, an aluminium radiator, an oil cooler, an electric fan and an alternator.

The chassis has been modified too, with coil springs added at the front, front disc brakes and knock-on wheels. The dealer separately has a Bristol 2-litre (1971cc) sports engine for sale at £15,000, which is not included in the price. Mileage and registration details are not given.
