Really? You're looking around that sort of price for the turbo install alone surely? I dont think its too bad when you work out of the cost on the Turbo install, all the parts installed.
Whats a 25k mile standard Zed of this year going for? 7k - 8k?
Imo yes mate. This is the way I look at it.... which will prob be different to alot of people. Its a 2005 car, so it is older, the good thing is it has extremely low mileage. Completely standard gt edition interior and exterior. So that leaves the twin turbo side of the car, which is naturally your biggest selling point. But is it really worth 8 or 9k to someone? Yes I know this is how much it would cost if not more to tt a normal 350z but for that money you are looking at getting a 370z and a much newer car.
This is just my opinion mate. It looks a very nice car and I am sure someone will be tempted but I wouldnt spend 16k on a 350z.
