Buying a car: Volvo V40 with 225tkm (BJ96) 2.0 136hp? What to consider?

Hi! Would you like to buy an “old” Volvo V40 2.0 100kw. Problem with the thing is that the car has already a good 225tkm down. From the outside it looks quite fine. I planned to try the car on the weekend. What should I pay special attention to, not to buy a “thinking moose”? – What are the changing intervals for the timing belt? – familiar problems with the model series/engine? – Is the engine already “finished” with 225000km? Thank you for your help!
