THIS BONNEVILLE SLE DEMANDS ATTENTION . Luxury with Attitude is how Pontiac describes the Bonneville, and the description could not be more accurate. The Bonneville is loaded with features such as dual zone auto climate control, power accessories (like the power sunroof), heated seats, and an adjustable steering wheel. There is a rip in the front seat, but other than that, the car has low mileage and is a great deal.
