Most hated question about your car?

The mistaken identity thing doesn't bother me.
My 67 Coronet 500s have been called Road Runners, Impalas, and Galaxies (they see the "500" and assume its a Galaxie). My 66 Sport Fury has been called a Thunderbird. My 68 Barracudas have been called Mustang, Corvette, GTO (I guess its the split grille), and the fastbacks are most commonly called Maverick. The one I didn't like though was the guy that came up and told me how nice my fastback was, and how he had a Pinto just like it.
