This car is very reliable! Since I have had it, only minor problems have occurred. I replaced the brakes and water pump around 90000 miles. other than that I just change the oil every 3500 miles.

General Comments:

I love this car. It starts with half a turn of the crank in any weather. I am a 20 yr old male. When I first got this car My Initial thoughts were, great I have a family car. This car has been the complete opposite of that. This car has great acceleration and handling. I take the high way to school daily. The car loves the on off ramps! I feel very comfortable going 50mph on a 25mph ramp. As soon as I get off the ramp, my gas petal is digging in the carpet. The 3.8 v6 accelerates to 90 mph in seconds. The cars tachometer stays around 2500 to 3000 rpm while traveling at 90mph. Being a male and 20 years old I tend to find my self leaving intersections with a cloud of smoke behind me. from a dead stop you can light up the tires and go through 2.5 gears while spinning the tires! Try entering an empty parking lot going about 35 and push down on the emergency brake while turning the wheel and flooring it. The Bonneville spins like a top, while smoking out the whole parking lot. The Pontiac's interior if fit for a king. It is very comfortable and convenient. I love the on steering wheel radio controls. The car is very roomy and comfortable for you and 3 of your friends. very road-trippable. I would recommend this car to anyone that wants a very reliable comfortable car, that will perform over and over no matter how much abuse it given.

Faults:

A/C Compressor made a lot of noises and then died. Needed to be replaced.

Timing belts wear rather quickly, and the engine must be lifted to change them due to the positioning of the motor mounts.

Fog lights burn out often, needing to be replaced.

Aftermarket accessories such as light covers, bug deflectors, body kits, etc are sparse. As sporty and nimble as this car is, it seems to have been overlooked by the performance accessory manufacturers.

General Comments:

The responsiveness of this rather large car is impressive.. the comfort of an Oldsmobile with the performance of a Pontiac.

Plenty of room in the front seats, the back seats, and the trunk.

Nearly every accessory and gadget a person would actually use has been included, such as in-dash digital compass, heads up digital speedometer, remote trunk release, flip out cup holders in the center divider as well as a small console in the back seat, rear passenger air vents.. it even tells you when your light bulbs burn out.

Luxurious interior, the power bucket leather seats are unparalleled. After adding a wood dash kit and plush floor mats it feels like driving a Lincoln or Cadillac, but with a GM Monster under the hood.

I used to drive a 1992 Oldsmobile Trofeo so am accustomed to a blend of performance and luxury, but lost it in an accident. I still miss that car, but I think I've found a new favorite with my Bonneville.

Where to begin? The biggest problem, which started to be noticeable 6 months ago, is that the back seat foot well floods when it rains. I mean it fills with several inches of water. I've tried sealing all visible cracks, but it still floods just as much. Water gets behind plastic seals and travels down into car.

The Check Engine light has been on for almost 4 years now. Had it checked early on, they told me it was a crossed wire and fixed it, but it came on again a few weeks later. The engine has not actually needed checking, despite this.

AC stopped working 2 years ago. Had it fixed.

Radiator leaks currently. I sealed it with that sealing powder.

Driver's door panel inside came loose as well as plastic strip near window. Glued it repeatedly, but eventually had to drill through and put in a screw to keep it from flapping in on me.

General Comments:

Temperature control system is terribly designed. To simply put on the vent, for example, you have to push a number of buttons, including turning the AC off, since it automatically goes on. Then you have to push push push the temperature button to find the one you want. It's almost like programming a computer while trying to watch the road at 60 MPH. This is the most poorly designed temperature control I have ever encountered.
