You could wait for the broad market to tank again and pick up a sale under duress if you're faster than Shelby, but absent of that, I agree with post above: Pic a color you like except Gulf and write a check for two bills. Gulf cars with low miles are very high $200's at this point in time.
I paid $158k for my red (common) car with 4800 miles on it two years ago. I wouldn't sell it for $200k now because I believe the prices will continue to climb - and because I absolutely love the car.
My $.02 from the cheap seats.
PS.. A CGT is still a long way $ away from a non-Heritage GT.
