Buick Park Avenue offers refinement and elegance, but it's a practical car. Quiet and luxurious, the Park Avenue provides a roomy cabin and a big trunk. Excellent road manners with surprisingly good dynamic capabilities make for an enjoyable driving experience. StabiliTrak is now available on the Park Avenue. StabiliTrak is designed to help the driver maintain control when the car is in danger of sliding or skidding, and it comes standard on the 2000 Park Avenue Ultra. Further improving safety are side air bags, which come standard on Park Avenues, along with new rear child seat tether anchors.
