Hi Rob,
Good luck on your search. Take your time and get the right one.
Not sure how much you know but here’s a few ideas….
Head gasket, make sure it’s done. Security, Ghost, disclock, tracker. Options, seats, wheels etc.
3rd party mods, eg Mountune, Litchfield etc
Mileage, service history and number of owners – particularly important on an RS.
Kenny, did you make that list for potential new owners?
