Too soon to tell. I'll wait until we can get a full, 360 degree view. A large part of the character of a car is the way the nose and tail look and we still haven't seen those yet.
From what we can see at this point, I'm not a big fan of the front fender vent. The rocker panel looks pretty plain and kind of slab-like. The roofline, particularly near the rear window and the Hofmeister kink is much more streamlined and has more of a fastback look.
