A 1994 Aston Martin Virage Volante once used by Prince Charles, the Prince of Wales, will appear at auction next month.
The 6.3-Litre Convertible will form part of Bonhams' Aston Martin sale in the UK on May 19.
The racing green four seater, featuring leather upholstery and green carpets, was loaned to Prince Charles by the Aston Martin Lagonda company from 1994 to 2007 or 2008, since when it has been on display at Aston Martin's south London headquarters.
The manual transmission vehicle has a £50,000-70,000 estimate.
Prince Charles is also the owner of an Aston Martin DB6 - the very car that newlyweds Prince William and Kate Middleton unexpectedly took for a spin on their wedding day.
The car was a 21st birthday present to Charles from the Queen in 1969. Run on British wine, the vehicle would make a considerable sum if it ever appeared at auction.
A Lanchester Straight-8 Limousine once owned and driven by King George VI sold for £29,325 at Bonhams in 2009.
It was bought in 1939, and the king drove his family around in it himself - which explains the sumptuous cloth seating throughout, instead of the usual leather for a chauffer's seat.
We have a superb Charles and Diana-signed Christmas card, featuring a photograph of Diana, Prince Charles, Prince William and Prince Harry, currently available.
Joint signings by Charles and Diana are extremely rare, making this piece particularly desirable.
Paul Fraser Collectibles will bring you the result from the auction next month.
