alfa spider buying advice

[e-eyes]

going to buy a 1997 R reg alfa spider 2.0 twin spark this week, just wanted a bit of advice on any weak points this model has, its got full history 65000 miles and the cam belt has been recently been changed, what commonly goes wrong with these cars and what keys should it have, i've only seen the red main key but the dealer assures me that theres another key, are keys an important issue with this car?
