I've also got a closer shot of that red 1955-56 Plymouth Belvedere I tried to get earlier.

The 1961 Chevrolet(possibly an Impala), that I had to settle for blending in with the '56 Pontiac Cheiftan.
A mid-1960's Rambler American/Rogue.
I also found another one I decided not to compress. Originally, I thought this truck from the New York City Department of Sanitation was either a White or a REO. Now I suspect it may be an International Harvester R-Series. I didn't compress it because I wanted to make it easier to identify.
FYI, Dennis is tilting her head to get around the flags at the construction site.
