Welcome aboard James.
Usual second hand car checks but also worth looking at; Bose head unit (make sure it plays CD's without skipping if you can), check all the car speakers work, see if the boot opens with a single press of the button (if it doesn't could need new struts or boot popper springs), make sure the fuel filler cap opens when the button is pressed, check the fuel gauge works properly (difficult to check without trying to put a full tank in though), windows should drop a bit when you open the door to get in & out... Can't think of anything else sorry. Have a read here; http://www.350z-uk.com/topic/77426-buyers-guide/ http://www.350z-uk.com/topic/22880-guide-for-new-memberspotential-buyers/
