Pontiac bills the Bonneville as "Luxury with Attitude." That's an accurate description, given its basis on Cadillac's Seville platform and available 240-horse supercharged V6 engine. If traditional Pontiac styling twists your crank, and you want a large sedan packed with performance and features, the Bonneville is your kind of ride.

2003 Highlights

The Bonneville gets only minor changes for 2003. Base SE models now sport newly styled 16-inch steel wheels and a standard AM/FM/CD stereo, while all models can be upgraded with optional XM Satellite Radio. Previously standard side airbags are now optional on SE and SLE models.

2003 Bonneville with 160,000 miles

Sean,09/29/2009

I am 18 years old and this was my first car. I bought the car two years ago with 130,000 and it ran great. I still have the car and it's still going strong with 168,000 miles. The only thing i have had to do with it is scheduled maintenance (oil changes, balancing tires, etc). Fuel economy is great for a 6 cylinder. It has a very smooth ride, and i like the comfortable leather seats. It

Great car!

I bought a 2003 bonneville when it was 8 years old with 86,000 miles and it was in perfect condition! Besides routine things, I never had work done on it. It got great gas mileage on the highway and was a smooth comfortable ride. I recently totaled it when we got a snow storm but I walked away completely fine! It still drove and the engine sounded fine but a lot of body damage was done.

Hate my Bonneville

belyache,06/17/2009

Purchased used, after 2 years I started noticing some transmission slippage from 1st to 2nd.. Then came the the transmission not engaging 1st. I had the transmission replaced, it worked fine for about 5 months. Now it is doing the exact same thing. It also has an annoying steering grind. I would not recommend this car. I have also heard others complaining of transmission problems with

My BONNEVILLE

Chuck Finch,11/09/2003

This is a very exciting and responsive automobile to drive and own, not only is it fun to drive it has class. You folks do not rate it high enough on your car ratings. This car is as good or better than the forign imports and you can take that to the bank. I will put my Bonneville against any of them. The Mercedes and Lexus's don't have anything over this car.

Should I lease or buy a 2003 Pontiac Bonneville?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
