Most hated question about your car?
The questions and comments don't really bother me most of the time because people don't know nay better. If I'm out somewhere or at the drag strip and a young person comes up and starts talking about my car I make sure to take time to talk to them and answer question. Without their interest in old cars our hobby will slowly die.
The sideways comments some azz makes as he and his buddies walk off are the ones that get to me. I generally ask them where their car is, what will it run and do they want to run it. That generally takes care of them.
I run in to this one every now and again, "if it was mine I'd do ........ and take ........ off and .........", I stop that one by telling them "it's not yours".
