2002 Buick Century Custom 4dr Sedan (3.1L 6cyl 4A)
It's been over 5 years (and about 75K) since I last rated this car and I'm still very happy with it. I now have 101K and she's running strong. Except for maintenance items the only things needed were new struts at 80K (driving in NYC can be tough). I also replaced the lower intake manifold gasket at 80K as a precaution (an $800 job) because the 3.1 is known to leak coolant into the oil eventually. I just replaced the original battery at 100K because I didn't want to chance getting stuck this winter. This car feels like 300K is doable. Mileage is still averaging about 25 mpg with over 30 on long trips. It has never let me down. A/C is still ice cold without ever being recharged.
Reliability and MPG.
GM should have fixed the intake gasket flaw before it hurt their reputation so much.
