The Colt is a '72 or '73.These pics are roughly 1969
Didnt know what the car was --- it "is what it is" so I stand corrected. Playboy first, then Dyer's blowers. Dyer is listed most often as the source identifying her in any case.The Colt is a '72 or '73.
As an aside, I remember buying the magazine back then. I think it was Drag Illustrated or a similar magazine. I did some googling to try to find what magazine and according to the internet, she was Gary Dyer's girlfriend
