The Ambassador 600 was a pretty significant car body—first American unitized body or some such, although it may have been unitized-body-on-one-big-subframe.
The 1949 Airflyte, the famous 'bathtub', had a long list of firsts; but I like the 41's looks better. There was a neat one years past at the Springfield Cruise—light gray over maroon 2-door. I'd take mine with a Tesla front-wheel drive subframe.
