Good price especially seeing it has a full service history. Amazing car, good looker as well, relatively peanuts for what you paid. Just drive it carefully and start a nest egg just in case, can't see any major repair being even vaguely cheap, what do reviews say regarding reliability and potential problems?
I'd find a dedicated Volvo forum, local or perhaps one in the UK and read up about them, normally a few things that if you watch them can prevent very expensive repairs.
With more specialist cars like this it can be significantly cheaper to get spares(even just service parts) from eBay.uk or European online parts shops, than from the local stealers, even after paying shipping and duties.
