2002 Buick Century Custom 3.1 from North America
Too many things go wrong
Valve lifters need to be done.
Gas gauge is not working properly.
All service lights are on.
A/C only works on high.
Hub bearings need to be done.
Catalytic converter needs to be fixed.
It's a very good car, but manufactured so poorly, it has a lot of things that go wrong with the car.
Would you buy another car from this manufacturer? No

These are mostly simple fixes, minus the valve issue you had.
Wheel bearings go after 100,000+ miles.
The climate control is just a blow motor resistor issue; max $40 part where I live, brand new.
The service lights are all interconnected, so since you have an ABS issue with the wheel bearing, it turns off the traction control, and also turns on the service vehicle soon light on. Fix the bearing and they all go out.
The gas gauge, although a pain, is just the float that has been replaced. $20-30 for just the float (takes some looking around to get though).
Your cat should not needed "fixing" as they are not fixable. If they are plugged, then it means you have had something foreign run through your engine, causing it to plug up. I'd check other stuff, as you could wreck a new one too, should you change it.
Centuries are great cars, good on gas and comfortable, and the problems they have are all minor (except the valve issue, but that's never gone bad on mine). Every car has its faults, and on most cars, their faults are lot more pricey than these cars.
