I'm a bit parted on this.
I reckon a 34 gtt might be better for you due to its age, but dont neglect a 32gtr. 34's are coming down in price and so are 32gtrs and you could even say they are around the same price(depending on quality).
You could even get a 33. they are common as, but due to the cheaper prices you could put your left over money into a few modifications.
32 Gtr is going to be my next car, but i enjoyed owning a 34 even though it was a 4 door, because it was a newer car (blah blah typical not a skyline experience with a 4 door).
Its up to you at the end of the day and theres plenty of helpful people that will be able to help you on this forum, just read around.
