I replaced the brakes when I first bought the car. I had to replace the brake pads 20,000 miles later.
At 90,000 miles, the car began kicking violently on the highway. I replaced a fuel injector and the problem went away.
The torque converter was replaced at 100,000 miles. I replaced the engine mounts and tensioner at the same time.
I replaced the alternator last month.
Many consider the Buick Century to be a car geared toward seniors. I agree, however, it is small enough to be enjoyed by younger generations as well. My car has survived two major wrecks, yet it lives on. So far, I have been very happy with the reliability and dependability that this car offers, and I would highly recommend it to anyone!
I own a 1990 Century V6 3.3L and it ran good. When I got it had 58,000 miles... now it has 92,000 miles and it just blew a head gasket... I do all the maintenance on it & I wash it about twice a week. I pamper that car and I've had to replace 3 alternators, a harmonic balancer, a fuel pump, and now like I said it blew a head gasket.. I don't want to get rid of it because I've put toooooo much money in it...
Buy a Plymouth Acclaim. It's a comparable car with better than average reliability and supposedly better than the Century. Oh, it's cheaper to fix too.
I own an 89 Buick Century Custom. I bought the car for $800, very poorly maintained, and over the last year I have only dumped roughly 700 in repairs into it. For 1500, I have a brand new exhaust system (entire thing was in horrible shape), fixed the door which had a busted lock, replaced the hub bearing, tune-up/transmission tune-up, replaced the entire break system from head to toe. The other two cars owned by my family (94 Ford Escort, 98 Chrysler Concorde), both suffered much worse in damage over the same period of time, the Escort blowing its transmission, Chrysler blowing about 50% of the car (it's a lemon).
I've had nothing but reliability from the car considering the amount of miles I dump into it... though I have also experienced the apparently common fuel injector problem... however I dealt with it by using the most potent fuel treatments and higher grade gasoline which corrected the problem (mine was bad enough that I would stall out on low grade gasoline).
