For 2003 Pontiac's flagship full-size sedan in three trims (SE, SLE and SSEi) contains more comfort items and audio entertainment options. Fine leather hides cover seats, with buckets standard in SSEi now with power lumbar and recliner controls for the driver's seat. In addition, there's a leather-wrapped steering wheel fixed with buttons to control the radio. XM radio is optional on all Bonnevilles. For power, SE and SLE draw from a 3.8-liter V6 plant that makes 205 hp, but SSEi uses a supercharger to boost output to 240 hp.
