Looked online about racing at LeMans [endurance] no mention of camaros/mustang/cuda/challenger , long ago Ford GT40 and modern GT Ford [awesome car] , Corvette wins - hordes of wins over the years .
I remember the showroom stock racing in the late 80's early 90's - Corvette's were kicked out due to no other cars could compete with them . A couple of Porsche 944 turbos did ok but that's about it .
A new series was started corvettes against corvettes , ferrari had plans of going into the series but didn't .
