Get it in writing. This car is NOT going to be a limited edition, although at first it will be, sorta, because of allocations.
I don't NEED to buy a Camaro right now. But dealers NEED to sell cars. Saturation levels will win out eventually. GMS will become available at some point. Trust me. New car models usually don't see it, neither does the 'vette. Eventually they'll come a knockin.
The dealer who can get flow through builds would be further ahead to honor it because let's say I could save 4K on a GMS price. I'd buy a plane ticket for $500, drive it home, and probably still save over 3000 for the SAME EXACT CAR! (oh, and the dealer STILL makes a profit, although they'll poor mouth you otherwise)
Depends on how lazy you are in order to get what you want.
