Nice shot! Of the three, my favorite is the '55. The other two are so fine...but the '55 gets me, perhaps because it was the first one. I guess it is the '57 that has become the icon of the fifties. In fact, even though Ford outsold Chevy in 1957, it's the Chevy that became the iconic car, not the Ford. It's the Chevy that i see at all the car shows and that has so many aftermarket products made for rebuilding it. I seldom see the '57 Ford at car shows.
I actually prefer the fins and side details on the 57. The front, however, I prefer from the 56. Albeit I still like it, I have always found the round grille and bumper area on the 57 a little odd.
Also, strange as it may be, I prefer the 4 doors, but that's a whole other set of wheels.
First, I HATE the annoyingly large size of the doors of coupes. Second, I don't like the fact that you have to lower the front seat to get to the back. I'm about 6 feet tall, so I don't particularly like crumpling up to get in the back seats, which usually offer little legroom.
