2003 Pontiac Bonneville

The era of the big boat sedans has long since sailed away, thanks to the 1970s energy crunch, but somehow the Bonneville has endured and managed to shift its image from old lady driving slowly on Sunday car to a modern, sporty performance sedan.  There were few major changes to the 2003 Pontiac Bonneville.  Once-standard side airbags are now only an option on the SE and SLE trims.  Front bucket seats get more power adjustment for reclining and lumbar support, and XM radio is added to the options list.
The 2003 Bonneville is sports-oriented, even without the supercharged V6.  The SE and SLE are aimed not at grannies, but at a younger family market looking for practical roominess and trunk space along with style, performance, and sporty handling.  The SE and SLE come with a 3.8-liter, 205-hp V6, while the SSEi features a supercharged 240-hp version of this engine.  A 4-speed auto tran allows you to switch between normal and performance modes.  The SSEi has sports suspension, rear spoiler, a heads-up display projected onto the windshield, power leather seats  and variable steering.  But even the SE gets supportive glove-like seats, cruise control, ABS brakes, power locks and mirrors, and remote entry.  The SLE falls somewhere in between the two, sportier than the SE, but with fewer standard features than the SSEi.
The supercharged engine is a favorite of 2003 Bonneville owners, who like its highway performance and immediate acceleration action.  The heads-up display gets high marks for allowing you to keep your eyes on the road.  The Bonneville features sporty handling, a smooth ride, and tight steering.  It is also very roomy, with a large trunk.  2003 Bonny owners complain about wind noise and lack of room in the backseats, particularly headroom.  Cupholders are badly made as are most of the plastic parts.  The way too busy dash is complicated and hard to get used to, say drivers.  Many wish the rear seats had a fold-down option instead of just a trunk pass-through in the armrest.
