OK, first off that's DSG Golf, so it contradicts what you have said one post ago.
Personally, 12,000 per year of the car, good full history, cam belt changed at 60,000 miles is essential and just make sure that the VW schedule has been kept, go to any dealer website and check it out. I got my golf at 70,000 miles, full history but it had missed it's cam belt and other bits, but only paid £7,250.
