Edmunds' Expert Review

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
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 also rides quite well at 120 mph. One of the only things i do not like about this car is that it is quite heavy, and does not stop as quickly as many other cars I have driven.
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. This car will eat them up for breakfast. I know I have done it. I work for Daimeler Chrystler and they don't make a ride this good.
Best Ride I've Had
SSEi 4dr Sedan (3.8L 6cyl S/C 4A)
Wish I could buy another car new just exactly like mine. 281,000 miles. Only major repair has been replacing intake and valve cover gaskets.... Knock on wood....Shooting for 350K with no major repairs...
Did lots of research on this car and reviewed this site alot. This car is AWESOME! It is stylish inside and out, inside dash is unreal, lots of fun gadgets and cool dashboard at night. The ride of my SSEi is like `floating` on air. Best car I have ever owned. Lots of fun to drive. Even let my wife drive it sometimes!

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.
