An interesting one - depends what work has been done on it to be honest. What is provided with the car? Just the service history booklet, or do you have all the receipts and proof of non-service work?
Assuming nothing was done other than service items, you'd be looking at a complete suspension overhaul, liquids (engine, transmission, differential), the clutch could need doing, gaskets (valvetronic, eccentric shaft, rocker cover), seals, potentially glass (windscreen likely to be pitted) and more.
Then again many of these things could have been done already.
The engine itself has been proven to be reliable beyond that, so I'd consider it. At c. £7k I'd expect to have evidence of a lot of recent work though.
