spotted this in the grocery store parking lot this evening. (cellphone camera only, sorry)
Looked pretty cool from the front:
Then I walked to the back .... and ugh, it was boxy:
It had a "Zimmer" name plate, never heard of that.
I got a bit closer and it said "84 Zimmer Convertible" on a plate affixed to the glove compartment.
The interior looked like a very plane Olds or Chrysler or some other standard big-3 car from the early 80s. So I guessed that it was a kit/conversion of some sort. And a Google search confirmed it.
Found a link to another 84... except for the name plate on the glove compartment this one would pass as a twin for the one I saw, and better photos also.
