i think your thinking about the daytona prototype series. there was that one year when the corvette one the daytona 24 hrs and that was cool. but in the ALMS there has always been competition, you have the LMP1 LMP2 GT1 GT2 and there are porsches, ferrari, astin martins corvettes, so much more then that stupid ass daytona prototype series bill france n nascar started.
