The spare part prices are quite eye watering, however that is side of pond. But you can get an idea of the cost of some of the parts that are you would need to replace over time, brakes etc having a nose around here.

As for issues to look for there was / is a problem with bellhousing bearing can't remember if there was a recall or if it's a fix on a case by case bases and which model year/s this effects.

One thing to factor in is the service costs as like the parts some seem a bit OTT, not sure of the prices back home but one of the big service costs is the transmission oil, which over here cost $100 a quart and in a transmission that holds up to 10 quarts it soon adds up, though most dealers will do it for around $80, bugger knows what the oil is made from for it to cost so much, maybe that's why Japan still goes whaling as they are needed for GTR oil.

If your not taking it to the track or launching it from every set of lights it should work of reasonable. The one big disappointment IMO is that for a 3.8l v6 twin turbo it sounds a bit rubbish, the transmission makes more interesting noises then again if you've ever had the misfortune to endure a long journey in a infinity g35 or a Nissan 350z it would seem that great sounding v6's isn't one of Nissan's strong points of late.
