A collector in Truro has bought a Daimler Super V8 LWB limousine that was owned and driven by the Queen, bbc.co.uk reports.
Ian Lillicrap paid £40,500 at the auction in Surrey for what he called "a little piece of history". He also owns an Audi that was once used by Princess Diana.
The four-litre engine car was used by the Queen between 2001 and 2004. In addition to the full-service history and original tyres, the car comes complete with photos of the Queen driving the car and the lamb's wool floor rugs - not mats.
When it was returned to the Jaguar Daimler Heritage Trust in 2004, the car had just 15,000 miles on the clock, telegraph.co.uk reports.
The car once incorporated several vehicle security features, including special lighting controls and a device that allowed direct contact with the Home Office and Downing Street.
While these have been removed, the Daimler retains a sliding holder that was added at the Queen's request - so she had somewhere to rest her handbag while at the wheel.
Auctioneer Fabian Hine said that Mr Lillicrap had got a good deal, in his opinion, despite the £40,500 price tag: "I think the new owner has still got quite a cheap motor car.
"I think it will increase in value as the years go by, particularly if he doesn't do any more mileage."
