About the only time the question or remark comes up is when I post a pic to a board. Even at Mopar gatherings, most folk don't ask. Only folks with the early A body fever, and they often ask "Is that a '63 or '64 car. On the other hand, when someone DOES ask, I figure I have a new friend!
For what it's worth, I was drawing pictures of the '63 Darts in my high school art class when they were new cars. I liked the '64's as well, but wasn't too nuts about the big front bumper and "foo-foo" trim. When the '66's with their slab sided front ends debuted, I thought they had really messed up! And as for the '67's - - well, I like 'em a lot better now then I did then.
