personally wouldnt buy from Keighley (as per xaviers link) i have been there and met the people who own it.
yes they do have plenty of nice cars, expensive cars, cars to die for but the people who run it well lets just say i got the impression they were some sort of indian mafia people (before anyone jump to any conclusions im not in the slightest bit racist).
if i had serious amounts of money i still wouldnt buy an import from them.
on a slightly better note
