I'm not trying to be argumentative with what I'm about to say, but IMO, "patina" is the most overused and ridiculous word in the car industry. It simply means wear.
Yes, there are many, many, many nice old, original cars with "appropriate patina" for their age. When it helps to qualify the car's originality, that's a good use of the word, IMO.
But, I think most of us have seen real POS cars that someone is trying to pass off as being special because it has that magical word "patina." In some of those cases, the seller is trying to get us to believe that tons of rust, a seized engine and a thrashed interior are cool because of the "patina."
It's almost as overused and mis-used of a word as "barn find."
I'm a word guy, so stuff like that bugs me.
OK, let the banana throwing begin.
