What is the Pontiac Bonneville?
The Pontiac Bonneville was a large American sedan that served as one of the more spacious cars in Pontiac’s range. Its character changed over time: the seventh generation was a mid-size, rear-wheel-drive car, while later generations moved to front-wheel drive and returned to a full-size role. The final generation ran from 2000 to 2005.
The Bonneville went through several redesigns. The eighth and ninth generations used the H-body platform, and the tenth returned to the G-body designation. Later models kept a four-door layout, with a roomy cabin and the practical shape of a traditional sedan.
