Trying to remember a car movie preview I had seen some time ago. It was two guys with beards (I think they were white beards) black hats, long black coats, sunglasses, and a black fastback car kinda like a Mercury with blacked out windows that they drove around in the desert? No I don't think it was "the car" movie. Could have been a ZZ-Top video for all I remember?

Could it be the ZZ Top: I Gotsta Get Paid Music Video from 2012?

No it is not (Super cool though!!!) It was more like a late 40's or early 50's Mercury and there were two guys in the car. Closest I've seen to a guess though Thank you!!!
