Well AUS did sell the R32 GTR back in the early 90's and there are ppl out there with the knowledge of the RB26DETT, so thats not gona put off from buying a R34 GTR.
Interior wise, Im not fussed, but I can tell you, it looks a lot better then some cars out there when back in its time and I love the Multifunction Display Unit.
R34 GTR's are very easy to take advantage of it power. As you know a full exhaust, panel / pod filter upgrades, an extra few Psi with a boost controller and a tune, you'd be ahead of afew cars.
Price wise, R34 GTR's are lowering. I have seen them priced from about $50 - $60 Thousand. A new 350Z is still around $60 - $75 Thousand.
