Ahhh - a '55! I know for sure '53 and '56.
'54 and '55 - those two years confuse me by the tail ends.
As a kid, this was a game played on the road. I always did get those two years mixed up, lol.
Also, the grills were different, but that's not obvious n the pictures.
I keep threatening the wife that her next car will be a restored '57 4 door hardtop in blue and white. Hauls a ton of groceries and won't be mistaken for every other POS in the lot. I think that she wants me to make good on the threat, tho.... so about that '63 split window
Oh, and, the 55 had a gas door, the '56 taillight opened up almost like the '57. See the door in the picture?
