I've just been offered £10k for mine, 04 26k miles, fsh, sat nav, tracker, rear park sensors, 19" antera alloys, cf front lip, 350z mats front and boot, cf engine cover, grounding kit, aluminium pack (entry plates and air vents, led tail lights, popcharger etc etc
i am tempted as i could probably only get £11k with a private sale
8K lost in 18 months
its not particular to the 350z, its the same with all cars
