This is a very interesting point and one that Neil and I have discussed.
In Europe the GT is far rarer and dare I say it, probably has a great sense of cache than any modern Ferrari or Lamborghini. While these cars are fairly common where we live, I have only ever seen 2 GTs on-road (not including the 4 I've looked at with the intention to purchase).
A Ford in the USA probably suffers from a little stigma (i.e. they make pick-ups, SUVs and econo-boxes... just how good can their sports cars be?), where as in England, and Europe as a whole, the GT is so foreign and exquisitely rare that it overcomes the badge snobbery with ease.
