Are A bodies more popular than B bodies?
A-bodies draw a lot of attention in my area because we seem to see a lot fewer of them than B-bodies. However, just given that if I go to a show, I will likely see far more B-bodies than A-bodies, I would say that the B-bodies remain more popular. Many A-bodies also had the wheels driven off of them and were subsequently rolled into the junkyards years ago.
All that being said, cool Mopars in general attract a great deal of attention at many shows because there are 10 times as many classic Fords and Chevys. I know of the same half a dozen old Mopars in our area that frequent shows. I even know of more E-bodies than A-bodies.
