MY EARS WERE RINGING FOR A REASON!!!! I can't believe it!!!! There is no real advantage to be taken. They use a single template for ALL cars regardless of make. All they have to do is put the proper stickers on the car to have a different "make and model." The chassis are purchased also. The only difference between all the cars really is what's under the hood. This is why I HATE Nascar so much!!!! I wonder if Walter Rohrl will drive for them?
