Any driving school cars are going to be rough. Honestly my budget if I go overseas stops at the ZR1. I don't know of many other cars with that level over performance at that price. I have a hard time justifying paying the same price for a 6 year FGT when I can get a new ZR1 but I guess it doesn't matter because either way an ungraded Whipple would be going on either one.
A FGT will keep, or raise in value, a corvette does not. Corvettes are pretty bad ass though, any new upper level model would work a FGT. But imo there will always be something about the FGT. Its on a different level of refinement/raw machine/uniqueness and still classy.
If I had to pick your original question it would be #2.
What kind of overseas contractor work do you do?
