A $200,000 house, which you work 25 years at average wage to pay back, is affordable, as far as houses go - especially at 5.5%. Houses typically range from about this level to about four times higher - though can exceed and undercut this level and, most important of all, almost never lose value - they retain it or appreciate. The average UK house is about $220,000. Cars, on the other hand, typically start at about $12,000 and go up to about $45,000, on average, though some are much higher and some are lower - but you can also buy an older one for much less, something not normally true of houses. This puts the Corvette, even if it were priced like that in the UK (which it isn't - try $85,000 for a base C6), at the very top end of the normal car-buyers range.
