There were 100 CanAm V8 Firenza's made for the South African Can Am series of 1973.

My father worked for GM and did some work of the Racing car run by Bazil Von Royan. (The also did a rally version) I have a photo of me next to one in our driveway. It was one of my fathers company cars.

Here is some more on the car:
