The Pontiac Grand Prix is available as a four-door sedan in one of three trim levels -- Base, GT and GXP. The base model comes with 16-inch alloy wheels, OnStar, a CD player, cruise control, air conditioning, keyless entry and power windows and mirrors. The GT adds 17-inch alloy wheels, foglamps, a remote vehicle starter and a trip computer. A Special Edition package, which features ground effects, body color grille, bright exhaust tips and unique 17-inch alloys, is optional. The GXP includes firmer suspension tuning, performance tires, an enthusiast-oriented stability control system, upgraded steering, a head-up display, unique trim and 18-inch alloys. A Premium Package, with leather seating and automatic dual-zone climate control, is also available on the Pontiac car. A pair of 3.8-liter V6s and a 5.3-liter V8 serves duty in the front-wheel-drive Grand Prix. In the base model, the standard 3800 Series III V6 makes 200 horsepower and 230 pound-feet of torque. The GT has a supercharged version rated for 260 ponies and 280 lb-ft of torque. Finally, the 5.3-liter V8 in the GXP makes a healthy 303 hp and 323 lb-ft of torque. All engines come with a four-speed automatic transmission; the GXP's has an automanual mode. Inside the Grand Prix, there's a definite cockpit theme, as the center stack curves to meet the driver and the gauges and displays are all in red. Control layouts are simple and intuitive, even the trip computer. The front seats are broad and comfortable, though taller adults may find headroom limited. The backseat is cramped, with a low bench and tight foot room making it a last resort for adults. At least there's plenty of cargo space, thanks to a 16-cubic-foot trunk..
