All of the above, PLUS:- One that hasn't had loads of owners .... the certain "tells" I also look for to see if a car has been loved or not is ....
a) Condition of the boot - original tool kit present?
b) Condition of the carpets / interior - is it fair wear and tear?
c) Does it wreak of ciggies and / or wet dog?
d) Are the tyres all matching (either in pairs or all four)
e) Are they quality - Dunlop, Vredestein, Goodyear etc. or Chong Wong Lee's?
If the car looks good on face value, but if you see major issues in these areas then I wouldn't be interested in it.

Service Receipts - call the garage to see if it's genuine and was there any work not done, that should have been. Moody Invoices have been known!
Have a look on Alfa Workshop's website for buyers guide - plenty of good info and prices here.
PS. Don't forget the V6
