Faults:

In the winter, the car will sometimes leak a little antifreeze.

The brake booster wore out at around 80000 miles, and began to pull my brake pedal down all the time while I was driving. I had to manually hold the brake up with one foot so the car would actually move. That is, until I got it fixed.

Random pieces of it are falling off:

1 - A plastic panel inside the car between the front and back passenger side seat completely fell off one day.

2 - One of the Buick logo wheel covers fell off during a period of heavy driving.

3 - Parts of both the driver's side front door and passenger side front door are coming off (inner workings of the door).

The A/C stopped working long before I got the car.

One of the automatic windows stops working sometimes. It'll probably wear out all together someday.

General Comments:

I love the way it runs. It sounds awesome while accelerating and picks up speed quickly. However, when I brake, the car jolts a little.

This car can withstand minor accidents very well. Case in point, I was rear-ended in a snowstorm by a guy in an SUV. My car was just pushed forward, it didn't really crunch up or anything. The tail light panel was smashed since it's plastic and the trunk latch was a little bent, but that's about it. I had no injuries out of it, I barely even felt the collision. This car is built like a tank.

There is a huge trunk. It goes very far back into the car.

I have noticed the car retains a lot of heat in the summer. Opening the windows doesn't help, the air just goes past the car, not in it.

The seats are the most comfortable car seats I've ever sat in. Very cushy and soft.

I love the shape and angles of the car. The back end is truly magnificent; the tail light panel looks beautiful when lit up.

General Comments:

This car is very comfortable, I am 4'11" and had no problem seeing out

With extreme high mileage, it had very few problems or repairs

The engine did not leak or burn oil ever

I could let the car sit all winter, and go to start it and it started on first try every time

It did rust pretty bad

It was in a couple fender benders and never effected performance.

It was my first car and best one so far (I've had 5 vehicles)

Gas mileage was average (I think around 23/mpg on country roads)

Rode like a luxury car; very smooth and quiet

I can't say enough about the car.

Faults:

The only problem I had with this car is for a while it sat and after that the transmission would seem to stick in gear and it would stall out. But after a while driving it it hasn't done that again.

General Comments:

This car is AWSOME! I love how you can put the petal to the floor and you can feel the power. Also very comfy to ride in and great heater and A/C. Overall this is a great car for anyone that loves cars and loves to drive them.

Faults:

Alternator failed, was replaced.

Transmission was would slip in first gear.

Choke valve wasn't functioning properly, car idled roughly in the cold weather.

Power window motors would overheat, windows had to be pushed up or they'd get stuck.

General Comments:

This thing had 130k miles when I purchased it for $500. It had most of the options. Given that it was 13 years old when I got it and that it was only $500, it only stranded me once in the year I owned it.

It was surprisingly comfy, it had a nice soft suspension and very plush seats. The V6, even at that age, was whisper quiet and made a decent amount of low end torque. This all made for a smooth ride.

Besides the window motors overheating, all of the electronics still worked properly.

The brake system was solid and the car stopped in a nice, clean line.

The rear facing fold-up seat is cool with your friends when you're a teenager. It was popular with my friends.

It also had nearly immaculate paint after being outside for all of those years. I was impressed with how well it had held up. It was a decent looking car.

For $500, that Buick was a great car to have while I saved up for something better. It was still working when I got rid of it a year later. Obviously it's not a very fast or sporty car, but I really did like it despite its faults (which all had to do with age). It was a fun car, and I'd buy another one in a heartbeat, especially a better-maintained example. If you're looking to purchase one of these, and it's been well maintained throughout it's life, you won't be disappointed.
