I dont know what you are saying there Perry. The prices shown are the prices at which real people have bought real cars but in mentioning your Range Rover pal you are mixing up two trades. The dealer trade you mention is the normal channel. As much as 90% of cars are on finance / lease and lease companies almost always sell through auctions to get rid quickly and cleanly. These auctions are where big dealers get their forecourt stock. Sometimes those auctions are limited to dealers only, though I have bought that way myself several times. Its also the standard sales route for the likes of "we buy any car" etc - they buy from you at auction price less a margin and then sell through the auction. Might a dealer then add a margin to cover his extra costs like the guarantee he has to give? Of course , so the buyer pays more and gets more.
But auctions are also used as in this case for the sale of rare / unusual items for which there is no volume trade. Morgan cars, or exotica like Ferraris are a case in point. At a time like this when such cars are not moving off the forecourt or even being accepted for sale by dealers, its the only way to establish what a car is worth. Give the auction lots of publicity, as in this case, and see what interest there is.
