You are a class act.
I do however feel joking about a car's pedigree in most cases not a good idea. Kinda like not making fun about "your momma" or messing with someones food.
I have owned some of the most commonly faked cars and know from experience how most people look at real one, as though "oh there's another fake". Make all the fun you want about my gut, garage, my comb over, my driving skills, but please not my L88.
