Things to look for:- regular services, because of the supposedly bad turbos. Smoke from exhaust, it's got a average fuel consumption display of the last ten resets so it's worth looking how it's been driven. Check the oil for water and vice versus, rear calipers sticking or seized one of mine is haven't got round to it yet! Check it's had all the recalls from Nissan. And get a spare key will cost you a fortune otherwise. Hope this helps.
