The R32s have the sleek look as well as the 'GODZILLA' look. They are lighter than the 33s
The R33s are newer cars but people tend to think they look too bulky and they are becoming a very common sight on australian roads. However, interior wise, the 33s looks much better, more spacious compared to the 32 and S14
S14s are nice cars after you dump some nice 19" rims and lower the car. It's a really fun car to drive. On the other hand, you won't get much room for any passengers at the back and if you're a tall person, this isnt the car to get.
My 2 cents
