Park Avenue ($32,980) comes with a 205-horsepower 3.8-liter V6 engine. Interiors come trimmed in cloth, with power windows, power mirrors, climate control, cruise control, automatic headlights and other convenience features. Anti-lock brakes and side air bags are standard.

Park Avenue Ultra ($37,490) gets a 240-horsepower supercharged version of the same V6. Trimmed in leather and wood, the Ultra adds heated front seats, mirrors with parallel park assist, a compass, moisture-sensing wipers, GM OnStar communications system, and other features. In addition to its more powerful engine, the Ultra comes with StabiliTrak traction control, a heavy-duty transmission and magnetic speed-sensitive power steering.

In mid-2001, Buick will release a limited-edition, special appearance package for Park Avenue Ultra. Exclusive Laguna Green paintwork will complement a two-tone Shale/Neutral interior with Southern Walnut inserts for the instrument panel and inner doors. Expect the package to include a long list of otherwise optional equipment.
