I was looking for a R32 GTR vs R33 GTR. I went for the R33. Bought one last week
Here is why:
1. Interior is much better, r32 seems too old
2. Drives/Handles better comparing stock
3. They are more rare. 16k R33 GTRs vs 42k R32 GTRs made
4. Better turbos
5. More roomier
6. Wider (I prefer wide cars, looks more staunch so this is more of an preference)
7. The underdog, everyone froths over the R32 & R34 so wanted something different
R32s might hold their values better. But if you are looking for the better car go for the R33. Did you know the R33 GTR was the first sports car to hit the Nurburgring in sub 8mins? Also, they never posted the R34 time around the ring due to actually being a bit slower than the R33.
