Personal preference aside, what can they do when a run of 500 cars generates interest from 5,000+ potential buyers? I don't think it's just an ego thing. I can see how being chosen as a buyer would be a bragging point for those who end up with one, but I don't see it as the driving force behind the "audition" process (maybe not the best term to use?). How can it be narrowed down to 500 in the best possible way?
I like the fact that they're trying to weed out the speculative buyers just looking for a quick buck by asking for proof that the car will be driven as intended. I remember the story of Ferrari doing this with the F50, where owners were forced to lease the vehicle for the first two years, and at servicing intervals, driving history would be downloaded from the ECU. If the car wasn't being driven as intended, the contract gave Ferrari the right to terminate the lease. Or so the story went, anyway.
Not that it's something I'll have to be concerned with, but I think I could find a way to be happy with any of the Ford GT/GT40 variants in my garage.
