The 2005 Pontiac Bonneville says goodbye this year but it goes out in style, with three trims offered – the SE, the SLE and the GXP. The Bonneville is a four door Sedan featuring passenger room for up to six. Engines range from a 205 horsepower 3.8-liter V6 in the SE and the SLE, to a 275 horsepower 4.6-liter V8 in the performance-oriented GXP. Front wheel drive and a 4-speed overdrive-enabled transmission come standard on all models. The Bonneville features dual zone climate control, cruise control, keyless entry, power accessories, heated lumbar seats and ABS.
