Same here, only F40 and Supra left.
The good thing is, I am quite sure this one will gets fixed very soon. And the reason is that current state will mot motivate players to race in tournaments, earn trophies (and pay gold for it :-P).
Some "solutions" are very simple too:
- fill each slot that is sold out right from the start (player has all the blueprints) with another car or with another stack of Supra and/or F40. Or even add stacks of "special events" cars, like La Ferrari or F-type?
- automatically refresh the store once its completely sold out
