I used to enjoy watching JT in that white Firebird Trans Am (the original) mix it up with factory moneyed Mustangs and Camaros. He was usually towards the sharp end of the grid - a hell of a driver.
SCG was a bit of dirt under the fingernails and not as glossy and upscale as R&T, but a lot of information to be sussed by a pre-teen hooked on sports cars. I was sad when it morphed into Car and Driver.
