Where can I sell my BMW M5?

I am looking to sell my M5 and would appreciate your advice as to how much I should get for it and the best way to sell it. It was registered on 30 June 2006 and has currently just short of 47,000 on the clock. It is in Interlagos blue with black extended Merino leather. It has been fully maintained by BMW, MOT until 30 June 2013 and has a BMW extended warranty until June. The list of extras is exhaustive and includes M6 twin spoke wheels, multi-fuctional seats, TV, comfort access, Bluetooth phone prep and telemat, Hi-Fi system by Professional Logic, through-load system inc. ski-bag, electric sunblinds side and rear, plus many others. In other words, it is fully loaded. It is a superb example and hardly run in. I would appreciate your advice as obviously I have no access to a Glasses Guide.

Retails at £17,900 with 66,000 miles; trade £14,450. Add £1175 for the lower than average miles. You could advertise it, which I don't advise because of the type of customer it will attract to your house. Or you could sell it anonymously via an auction house, such as BCA. They will probably advise a 'Top Car' auction rather than www.sure-sell.info that makes more sense with lesser cars. It will probably be bought for export, to go to a RHD country such as India, Pakistan, Malaysia, Thailand or Indonesia.
