Well its pretty god awful rear end so its the designers problem, doesn't mean its not a good car though. Over complicating designs will almost always make things look bad. (Pontiac Aztek is a good example not many like) This is a million times better...
Every post in this thread is the car's problem, mine is no different just because it's something you like. Also, modern Zagato cars have some of the most hideous rears I've ever seen. (imported from here) (imported from here)
Actually the bonnet does look truly awful. If that was flattened out a little though it would look fine.
I know I'm gonna get a lot of hate for this, but... When I was young, I used to HATE the big red things surrounding the taillights, but now that I look at it more closely, the Countach's rear end is just ugly in general. That being said, the rest of the car looks fan-fucking-tastic! Quite ironically, though, I think they look much better with that ridiculously ostentatious rear wing installed than without it.
You'd probably like the 25th Anniversary version, then. (imported from here) Ignoring the lack of a wing, as some models came with that, but the general design and brakelight surrounds.
