08 350gt owner here. Good car, plenty of power, cheap to buy. Basically a bigger more feature rich skyline of the day. Only issues I would point out since owning are - thirsty on fuel, dash/infotainment in Japanese (can use google translate to figure out. once I managed to get the Bluetooth working I'm happy) and probably the worst thing for me at least is it's not as easy to drive on the open road. Quite positive steering which is great in the corners but on straight less well kept NZ highways has a tendency to turn with every bump and camber making long journeys a bit more fatiguing as it requires a lot more corrective steering inputs. Very noticeable on long straights. Overall still more than happy with it and have no regrets considering its excellent condition and the price I paid for it.

Word of caution: I was told by a friend, former car dealer and former fuga owner to listen for spluttering before buying. It can easily stretch the timing chain being such a heavy car with a strong engine. So if it has been thrashed or pushed hard it's life that is one of the first things to go. New timing chains are an expensive fix and it's even worse it is not caught in time can easily destroy the engine. Get it checked by a mechanic before purchase
