Bought as a family car. Lots of room and great trunk. The 3.8L V6 was well proven and it has been great (skip the 3.4L). I got the fully loaded sport package then upgraded it with police alternator, SLP rocker arms, SLP dual exhaust, K&N intake, slotted brake rotors & performance pads, and tuned ECM (LSX model). Have been a fanatic about maintenance & fluid changes (synthetic lubricants everywhere). No trouble except for clogged cat at 70K. At 100K it still runs and looks like new. Plan to keep it to 150K miles.
Power, visibility, ride. Easy to self maintain.
Wish GM left this car alone. The 2006- later years front end looks like the old ugly Lumina.
