CAR SHOW Ebody Jerks turn their noses up

So seein' as I'm in one of those moods what bothers me more is when I walk over to somebody on the street who has a nice old car and compliment them on how great it looks and before I can breath they tell me "IT NOT FOR SALE". Don't understand why someone can't take a genuine compliment with out lookin for an ulterior motive.
Come back with, "Good,cause I ain't interested in buying it!"
