I only found out recently that the 964 was "unloved", now that they are getting popular. I always liked them much better than the over-inflated 993 and onwards cars. It was that concavity in the rear flars that made me weak in the knees.
This is the sort of thing I mean:
Plus the 964 still had the proper, upright headlights of a true 911.
However, a flared 993 like a GT2 with Speedlines is good looking in my opinion.
