Big skies, big open country, Big Macs. America likes all things big. Perhaps that's why the full-size Pontiac Bonneville has endured for almost 40 years. The 1991 Pontiac Bonneville looks like a retirement car that clogs up the streets of Florida, but it also makes for a wonderful family car. The base LE, SE, and SSE trims all feature a powerful 3.8-liter, 165-hp V6 engine and 4-speed automatic. Though off-the-line acceleration is sluggish, thanks to the auto tran, once the 1991 Bonneville hits highway speeds, it is a quiet, smooth, and reasonably fast ride. Though the LE comes standard with few comforts, the SE and especially SSE are decked out with all the luxuries to make long car trips enjoyable, such as cruise control, power seats, fog lights, ABS brakes, lighted entry, and headlight cleaners. And the Bonneville is great for long trips, as it seats six adults comfortably. No more griping about crossing over someone's imaginary line in the backseat. 1991 Bonneville owners love the precise handling and smooth performance of their sedan, and are impressed with its speed and engine power. The car seems built to last, able to repel impacts safely. It is a tank, after all. Owners also love all the interior extras. Some complain about peeling paint and the scarcity of parts as these cars get older.
