There was a series of them, and they were all named "Homework". The only pic I can find on the internet, is of an SS/JA '65 Chevy II:
I'm pretty sure there was a '60s Corvette they ran in the '70s.
And the one that I remember from the '80s, was a very clean '69 Camaro convertible Stocker, presented as an SS/RS Indy pace car, with a white convertible top, white paint, and Hugger Orange stripes. I think it had the orange hounds tooth interior, so it was probably a real Indy pace car.
