Yes, is an american movie from late 70's, early 80's. Just watched and is not the one. But thanks anyway.

'Le Corniaud' has a similar plot with hidden gold in a Cadillac. https://www.imdb.com/title/tt0057967/
But I guess you're looking for an American movie.

Hi.

Hope you gus guys can help me.
I'm looking for a movie wich i saw it in the 80's that is all about stollen gold and they try to pass it in the car's engine.
There's a black guy stealling cars and he say "you see a peach, you got to pick it" and i think he's talking about a Mercedes c107 or r107.

Thank you all.
