Well after viewing a few more i have finally bought one, due to pick it up on monday
Its a 54 plate, gunmetal grey with the Alzean leather and full gt pack. Only thing not on there is the rays but i may have a plan on that one! 48k miles with full nissan history, 2 owners, 3 keys one with the original nissan dealer tag! Also has the plastic see thrugh guard on the front end to protect from stone chips Not had a spot of paint on it and leather looks like new. Really glad i have found a good one after looking at a lot of rough cars, it was over my budget but thought it worth paying a little more to make sure resale value will be good. Even has a 2 year warranty on the engine and box the previous owner took out.
And where did i find it? The worst possible advert i had ever seen for a car, but thought i would look anyway lol.
So, fingers firmly crossed monday i shall be a happy Z owner
