The 2003 Buick Park Avenue Ultra gets a lot of updates this year, including the retro portholes above the side fenders.  Most notably, the supercharged 3.8-liter, 240-hp V6 engine and 4-speed automatic now comes standard with the previously optional Gran Touring package, adding a firmer self-leveling suspension and rear stabilizer bar.  Adding on to what you get on the base model, the 2003 Park Avenue Ultra features stability and traction control, a tire monitor, auto-dimming mirrors, and rain-sensing wipers for near effortless driving.  Rear parking sensors are optional.

Other upgrades from the Base include a trip computer, new 17-inch wheels, turn signals in the mirrors, a CD player, a front bench seat that expands seating to six or five with a fold-down console, heated seats and mirrors, OnStar, and wheel-mounted audio controls.  If you need to be pampered further, you can add on a sunroof, heads-up windshield display, and a CD changer.  The roomy comfort is great for family vacations, but drivers really love the extra engine power and improved acceleration in the 2004 Park Avenue Ultra.  The center console cover is a bit hard to open.
