I couldnt decide either.... So I built a '30 coupe with a Flathead
To answer your question in my opinion. I was brought up around Model A's from the day I was brought home from the hospital. I came home in a '31 Standard Phaeton in 1984. So Im rather partial to them myself. But I was also extremely fascinated by Flathead V8s as well. So I guess the decision is up to you and your personal preference. There are strong support groups behind both sides. Model As are a bit more plentiful and popular, but early V8s are nice too!
