Ah, the obligatory 'clean car'...rather a lot of money for a 13 year old car. Other than rust, its the mechanical (especially), electrical and structural condition of the car that counts for old cars. I would also check if those tyres were actually replaced and not by part-worn or cheapo Chinese (i.e. never-heard-of make) dicth-finders. You'll need to factor in the likely cost of replacing the suspension coil and exhaust within a year as well.

Probably worth you giving more details - specific model (which can make a large difference in the price), where it has been serviced and how often (check the service book, and preferably, with VW as the first can be easily forged). Have you done a mileage/history check for accidents and thoroughly checked the car over (by you or a knowledgable friend/AA/RAC mechanic) for the mechanical (especially), electrical and structural condition of the car and all its gizmos (electric windows, heater/AC, ICE, lights)?

No picture BTW. Excessively work upholstery can also be a clue to a clocked car (expect some wear for a 13-yo/95k car). I personally think its over-priced, even if it checks out OK on the above.
