Looks wise it has to be the R33 & those 3 above look stunning. One of my mates has the R33 & another has the R32. I was passenger on track in the R32 the other week then I drove the R33 on track that afternoon and other than the 150bhp difference I couldn't really tell much difference. I was due to drive them both back to back around the track but the R32 caught fire in the morning session

R33
They are both very capable cars and the R33 with 365bhp was a lot of fun on track, I love them and my next car will be a skyline, I just can't decide which one.
