Exactly.
It's pitched as a bargain because to buy it is. To run it's average / cheap for the company it keeps.

People buy it as the initial cost is so low. Even Nissan has said it is a supercar and is serviced as such. The 350z and 370z are basically large Micra engines with bits bolted on (as they are NA) and dont throw down a whole load of power and dont have complicated drive trains. The GTR is a whole other animal completely and should be considered as up there with Fezza and Lambo as a supercar.
I was seriously tempted by one until I realised (a) I'd need another mortgage to finance the running costs, ( it doesnt fit in the garage, © depreciation is massive as people buy them, run them til the first few services are up (some free I beleive) and then try to shift them.
At one point, second hand prices were going up for them which was crazy, im pretty sure the guy at EVO sold his for more or less what he bought it for 1 year later. (Although i could be quoteing my memory completely wrong!)
In a few years time the prices of servicing will be right down, its just that now they are still rare, still pricey so they know they can charge a load.
The best thing about them though, is as they have seats in the back they make a perfect "Family car" when your gf/wife/spouse starts to moan you need a 4 seater!
