This has been a solid and reliable car for the past 2 years. No major problems. I broke the Turn Signal switch once and that was a pain to get repaired. I also just recently had the O2 sensor become disconnected which caused me to get it towed. I didnt know what was wrong, but took my mechanic less than a minute to fix. Other than that its just been the usual maint. with the car.
Have had this car for quite a while. The 3.3L has probably been its saving grace. Now at nearly 13 years old, it's still going. Original motor and transmission at almost 270k miles. No real major repairs save the harmonic balancer pulley and the heater core. It has enjoyed eating alternators in the past 5 or so years-- 3, I believe. And the cruise control stopped working, but would require a new computer and simply would not be worth it at this point. All in all a great car, especially considering how long we've had it and how many miles it's traveled. Will only hope the next car I purchase will be as reliable.
In 1997, I bought a 1993 Buick Century with 160,000. miles for 2500 dollars. In 2004, the car had 253,000 miles. The six cylinder engine enabled me to buy a cheap high mileage vehicle, drive it for 7 years and put 93,000 additional miles on it. Like the consumer reviews state, the car does have so-so brakes. I must always keep 3 car lengths behind the car in front of me to allow for adequate braking. However the so-so brakes slowed me down and may have contributed to the longevity of my 1993 Buick Century Custom. The trim inside and outside the car does have a tendency to fall off, but who cares about trim. My passenger-side windshield wipers and power windows failed at about 200,000 miles.
We bought this car 3 years old with 30K miles on it. Great power and handling. Mileage 18-20 with V6. Just put a new tranny in it at 140K miles. This was the only time I have had to call a tow truck with this car. Only other problem has been with sensors. Would have had dealer fix this when I first noticed hesitation if I had any idea... As it is I did not. Ended up replacing numerous sensors (replaced O2 sensor several times) and having various repairs due to sensor gone bad. We're now up to 2 kids. The back seat doesn't allow much room for an infant car seat, so we're going to trade in the Buick on a mini-van.
