I was surfing the Old car advertising site and found this 1964 Pontiac Tempest ad, in the shot of the car in traffic with the woman with her head leaning out the window there’s a car behind the Tempest that I can’t identify, it’s not a TBird, I also thought it might be a Cadillac concept car but none that I could find, it could be something foreign, I’m scratching my head…?
