Stop in for a cup of coffee

Pressure washed the engine compartment on the Cuda. Everything except the rubber is factory. how the hell can I prove or dis prove this thing has 6 k on it. There are signs saying yes but then the re paint is a mystery. Had Chuck (the body guy) come look at it and he is scratching his head. The rot makes sense used and put away never washed.
I've seen people repaint brand new cars..
