Dan - R33 GTR was a decision i made a long time ago (prior to the R35 coming out). I could have brought pretty well anything the safe side of 100k back then and looked at R32/33/34 GTR, BMW M3, HSV, FPV, Evo's, even an AMG Merc. A friend took me for a ride in his R33 GTR (+500rwhp) and I was sold on a GTR. I personally like the R33 shape as i think it will age well and it was more roomy than a R32 (I'm a reasonably big guy) and it was a fair bit cheaper than a good R34 at the time, leaving room for mods I knew I would make. Hence R33 GTR it was. My biggest regret with the 33 was declining an opportunity to buy a low km 400R because i had already sunk money into my car and it was already faster than a 400R. Hindsight - damn silly decision.
As for a R34 GTT, not my cup of tea. I can appreciate the appeal as for what they are they are far better than the local product even if they a re nearly 10 years older. Bang for buck and a compromise - why not. I am lucky to be in the position of having several cars so I can keep the fun to the GTR and daily duties to something more mundane. Need to put a smile on my face - go home, change cars.
GL with the decision.
