Still, they competed directly against each other in SCCA and at the drags and like the L 88 & ZL 1, all you had to do, is have the money to buy one and it was yours.
Now, if you had a rule that said a minimum of 1000 cars had to be made, I could see excluding cars because they were "special".
Even 1000 cars isn't very many cars, in a Big 3 line up.
That said, it is JMO and I don't race in the organization but, it does seem a little unfair.
