The usual stuff . Cambelt history should have been done twice on that mileage.£400 at the indies!
Steering/suspension bushes (listen for squeaks and knocking) check the electrics all work and the dash lights all go out when it's started. Have a look underneath see if there are any signs of rust on the sills or the floor.
The exhausts have a tendency to rust .
The other is the camshaft variator (diesel like rattle at tick over)
Just use a bit of common sense rather than your heart

Hope it's a good one :thumbs:
