After all, they have probably missed out on all the other pleasures of ownership. Think before you buy, not when you want to sell. By the way, if you are disappointed at the second-hand prices you are offered when you wish to sell, please don't take shoot the messenger. By this I mean that if you are upset because you realise you are faced with a loss, you should think about this before or at purchase time. You volunteered to buy, nobody forced you to, nobody is forcing you to sell or accept the offer you are given, don't take it out on the poor dealer.
Most dealers pay reasonably competitive prices.
You can always shop around. We also see this happen time after time with other consumer purchases, particularly jewellery and watches. We note that auction prices were cited. It is strange that many people automatically believe they will get a better price at auction, or that they will get a better buy at auction. While we would not argue with the theory behind auctions, that they find open market prices, we believe many people would get better deals selling or buying through a dealer.
