This has been covered many many times, but here goes:-
Roof rail corrosion, corrossion on bottom of doors, dead pixels in the DIS, central locking issues, MAF, good service history important, Cam belt and water pump changed at 60,000/5 years. thermostats, temp senders, standard radio volume control dies affter several years.
High mileage not an issue provide car has good history and been cared for. Lots will have been remapped. Always always buy on condition rather than mileage. These are great cars but not without faults, but we all love em.
Hope this helps.
