When it comes to my car, I hear everything from
"this has got to be an original" to
"is this one of them Factory Five kit jobs?" 
None of it means anything. It's gotten to the point now that I do not correct anyone who is preaching to the group he's with. I just let them walk away thinking it's whatever their friend assured them it was -- even an "old Corvette." I only take the car to maybe one or two shows a year now. Usually big, holiday related shows where I know the people/politicians that are putting it on and I know the money is going to a good charity. I will say this, the level of "Cobra/Replica/KitCar Awareness," of today's car show audience, is significantly lower than it was ten years ago.
