-Volvo S70, or S60, not RWD but should cover all the other bases.
-Infinti I30's are an excellent deal, but no manual tranny
-I'd look at a BMW 3-series, not sure if you can get an E46 in that price range but I think so.
-I'd steer clear of VW and Audi, unless you like spending all your money on parts and trips to the stealership.
