I know where two of the IROC TransAms that never got raced are as well as the second gen Camaro that Andretti wadded up back in the day
They actually belong to a guy that runs a shady little used car lot in Ewing. He is a nice guy and takes great care of the cars. One late model is a super speedway car, one is a short track car, and the second gen sits in road course trim but when he bought it enough spares came with it to set it up for any configuration.
