I was going to make the suggestion, if you want to buy an NA, buy an R34 one. Don't waste your time in the 32/33 camp. The 34 in the cabin is a much better car.
In saying that, I'd also look at what you're going to want to do in the near future. Personally, I love the fun of getting away with a bunch of mates, throwing a bunch of gear in the back of a car and heading for some fun out bush, where know most P plates that are into cars, you'll have some fun in paddocks etc and just flogging the car around. For example, heading up to nelsons bay etc, you can actually legally drive on the beach... I wouldn't try that in the Skyline...
