Welcome to the club! A very good choice in car!
First thing that is important, check to see if it has a full service history, also find out when the cambelt was last done. Listen to the engine on a cold start for any tappity sounds, generally it's usually piston slap which is harmless and goes away when the engine is warmed up but if they persist then there are problems.
If you take it for a test drive, and make sure to thoroughly go through the gears and feel for any notchiness. Could be a sign of an abused box... sometimes changing gearbox oil can help, depends on severity. Try and take it over some bumps and listen for any knocks or rattles!
