I know what you mean, when asked if my car was a "kit car" I always reply "No, kit cars come with instructions" and I haven't found any yet, its a replica body". When the late models show up makes me want to say, "So what lot did you pick it off of, and hows the payment?"
Wait till you get your roadster out and save me a nickel every time somebody says "Nice T-bucket" (nothing against t buckets, it just isn't one) Or "Nice coupe".
Educating the ignorant is sometimes a tougher lesson for the educator than the learner.
