When you bear in mind the different price comparison in UK with, say, McLaren or Porsche it's harder to make the case for Corvette.
Over here nobody buys a Corvette as the automatic default choice - the Germans have got that stitched up. You need to really WANT a Corvette to pay so much money for one and then have only one dealership in the entire country. It's not exactly a convenient ownership prospect for the majority of people.
