American comedy in colour from 1970s. Not as late as 1980.
I believe they wanted to steal some jewellery, gold or similar. Do not think it was money.
There was some car chasing, with some (red?) car I believe. IIRC the driver was rather enthusiastic. For some reason I remember a record (LP) with some car engines or similar, but not sure how it fits in. Some / all wore flared pans (thus I believe 1970s). For some reason they also had a fight with the police and believe there was some helicopter either chasing or flying the robbers. Believe they also used some bombs or smoke bombs in a sand-pit or ravine.
It was a contemporary film set in some (bigger) city. Do not remember if they were successful or not.
Thinking about it I now believe it was a diamond heist. Scribbling down words on a piece of paper I ended up with:
Heist, helicopter, US-City (New-York?), Bombs in sand-pit, diamond, fight with police, car chase, LP-motor, scarf, bananas, elevator, comedy, color, 1970s, flared-pants, sunglasses, suits, ties, summer, action.
Not sure how or if all the words fit in. Believe the city was New-York, or some similar to it, (Sky scrapers etc.).
