Buick offers two models: Park Avenue and Park Avenue Ultra.
Park Avenue ($34,075) comes with a 205-horsepower 3.8-liter V6 engine. Standard features include a cloth-trimmed interior, power windows, power mirrors, automatic climate control, cruise control, automatic headlights and other conveniences. OnStar, anti-lock brakes (ABS) and side-impact air bags are standard.
Park Avenue Ultra ($39,225) romps with the gusto of a 240-horsepower supercharged edition of the 3.8-liter V6. Trimmed in leather and wood, the Ultra adds heated 10-way power front seats, mirrors that automatically tip downward for parallel parking, a compass, moisture-sensing windshield wipers, GM's OnStar communications system, a premium stereo, and other luxuries. To complement its more powerful engine, the Ultra comes with traction control, StabiliTrak stability control, a heavy-duty transmission and Magnasteer speed-sensitive power steering.
Ultrasonic Rear Park Assist ($295) is a useful option that aids parking and enhances safety by sounding a tone and illuminating an indicator as the rear bumper approaches objects. Also available is a Head-Up Display ($300) that projects vehicle speed onto the windshield.
A Prestige Package ($2240) adds many Ultra luxuries (but not the supercharger) to the base Park Avenue. StabiliTrak ($495), the Gran Touring suspension ($285), and a sunroof ($1,095) are optional for the Park Avenue.
