A 1954 Bentley R-type Continental Fastback – one of just three right-hand-drive automatic examples built – will go under the hammer at Silverstone Auctions' Lancaster Insurance Classic Motor Show sale on 15-16 November.
The late D Series car is estimated at £800-900,000.
The Bentley was delivered to Alan G Clark and was highly specified with an automatic gearbox, electric windows, Smiths heating and twin foglamps. A top-of-the-range 4.9-litre engine was also fitted.
The stunning Mulliner & Co aluminium coachwork was built onto a Rolls-Royce chassis, and has been kept in fine condition by its current owner.
"This car is a beautifully styled masterpiece, offering gracious classic motoring with just a hint of modern convenience," said Nick Whale, managing director of Silverstone Auctions. "It is beautifully presented and is testament to the pampered existence it has enjoyed."
