Redesigned for a mid-1999 debut, Buick's full-size, front-drive family sedan has been the best-selling full-size model in the U.S. market. Slightly taller and wider now, on a longer wheelbase, styling resembled that of the pricier Park Avenue. Rivals included the Chrysler Concorde, Mercury Grand Marquis, and Toyota Avalon. New standard equipment included front side airbags and an independent rear suspension, along with remote keyless entry and an automatic-leveling suspension. Antilock braking remained standard, but now had an all-disc setup. Traction control was an option. Sole powertrain was an unchanged 3.8-liter V-6 and four-speed automatic transmission. Both Custom and Limited models were available with a Gran Touring package, including a firmer suspension and 16-inch tires (instead of 15-inch). The redesigned interior offered a split front bench or optional buckets, with a center console. Safety belts attached to outboard front seats, which had a "catcher's mitt" design, claimed to reduce whiplash injury. New options included a trunk-mounted 12-disc CD changer, power sunroof, and rain-sensing wipers.
