The 57 tail lights, in my opinion were more attractive, as they filled in the entire end of the fin.Technically, not a C body, but IMHO, the '58 Chrysler was about the best. The '57 had a lip over the windshield that was removed in 1958.

I agree that the tail lights look better on the '57, but since they were looking for "sleekest", the '58 doesn't have that lip over the windshield. They claimed that the lip limited top speed for the '57 300CThe 57 tail lights, in my opinion were more attractive, as they filled in the entire end of the fin.
