Great Vehicle

Bought this with about 26,000 miles on it in 2008 after my mechanic gave it a clean bill of health. Had it for 18 months and haven't spent anything on it except for gas and routine maintenance. I average 24 miles/gallon, but get 30 when I do all highway. That's 600 miles from one tankful on long drives, very impressive! Performance is great with a very comfortable ride and every feature you could want except a nav screen and an MP3 player. Handles well and looks great. Best car I've ever owned.


Handling is poor in winter

Love the car in the summer but hate it in the winter. Handles really bad in snow with the 17 in tires. Had to buy another car to drive in the snow.


Most Reliable Car I've Owned

The Pontiac Bonneville has far exceeded all of my expectations. It's gas mileage has routinely been 30mpg or more (I do drive mostly highway). The Bonneville is far roomier that I thought it would be. It has a wide stance and drives very smooth (like a Cadillac); but then again, it is just like a Cadillac as they were both built down the same line at the GM Detroit Hamtramck Assembly plant (where the Cadillac DTS and Buick Lucerne are built).


Reliable until stuff starts braking!!!

I've had to deal with blown head gaskets, multiple tranny leaks,and the traction control went out.


Great car, but the seat is killing me.

I like everything about this car, but have bought a lumbar support for this car. My back has seen batter days. Seriously! I have been to the chiropractor several times, and if I don't get the lumbar pillow adjusted to the right spot I head back to the back cracker. Anybody else have this problem? I am 6' 4" and also wished the seat would move back farther.
