In order I prefer 34, 32, 33. I've bought two 32 GTRs. Want a 34 but might hold off any new car purchases until the 2007 GTR is available.
But if I won lotto in the meantime I'd buy the Mines R34 GTR M-Spec Nur. The one on carsales has dropped from $195,000 to $165,000. I'm still a fair way off though.
