yeah, the price may be down at the moment.. credit crunch and all that... but property prices being what they are, someone can afford cheap properties, reposessions, auctions etc... once the credit crunch is "over" those people are going to make an awful lot of money... then the prices of powerful supercars will go back up again....
give it 6 months, see if the V12 vanquish S is still affordable for us mere mortals :-)
