er depending on when the car was registered,ie early part or latter part of 2003 it will not need the cam belt changed until 60k(DO A SEARCH ON HERE FOR CAM BELTS),something that you will not be able to check if its working or not is the rear booster heater(ITS FAR TO HOT NOW)as dave says it will either be a 115/or 130 bhp,negotiate over the tyres,doubtful whether your be able to tell if the drive shafts need replacing but as mentioned bear this in mind?if in doubt take a decent mechanic with you to give the car a good going over,BUT IF ITS FROM A GARAGE get these things checked and make sure you get some sort of warranty with it. OH and make sure you get 2 keys with it,COZ THERE BLOODY EXPENSIVE. HTH.
