Hi Oliver,
The 4.2 is a very reliable engine and at that mileage will have very little wear.
The main thing to check is that all the electrics work and there is no faults.
60k the gearbox needs a oil and filter change.
Check that the “duckbill” modification has been carried out for the a/c drain, if not then the passenger side carpet will get wet at some point.
The valley pipes for the cooling system are a potential weak point though again, at that mileage, shouldn’t be a problem.
All in all, a nice car but do ask to see as many receipts for any work carried out.
Good luck.
