Hi PD, Welcome.
First and foremost, service history and cambelt/variator change. Search this forum for cambelt and you will understand why. If it has not been done it will cost you £400-500 for the whole thing @ Alfa, if you don't then it can get costly.
Alfa had the cambelt change at 72K, but it broke a lot and they changed it to 36K/3 Years...check it out. Also check the oil levels, low and walk away...engines use a bit and if run dry they might be nasty in the future.
Other than that get a cool colour, lusso spec if possible, selespeed is good, so have fun.
