The Park Avenue is large and luxurious, Buick's flagship. Though the Park Avenue is dated, it is a solid sedan, offering some of the latest technology for safety, convenience and communication from General Motors. Equipped with a supercharged V6 engine, the top-level Park Avenue Ultra is fast, stable and satisfying to drive. It's surprisingly agile and responsive. It's equipped with StabiliTrak, a superb active safety system that can detect the beginning of a skid and help keep the car on its intended course by pulsing individual brakes.
