A supercharged version of the 3.8-liter V6 engine means the 2007 Pontiac Grand Prix GT hits 260-hp, a 60-hp boost from the base version.  The GT comes only with a 4-speed automatic, but does feature 4-wheel ABS and traction control standard.  Stability control not available.  The 2007 Grand Prix GT has bigger 17-inch alloy wheels and foglights, which you won't find on the base.  Dual front-side airbags are standard as is a new tire pressure monitor.
Adding onto the power features, keyless entry, OnStar, and 6-way power driver's seat on the base model, the 2007 Grand Prix GT offers remote start, a trip computer, cruise control, and steering-wheel mounted audio controls.  A CD player is standard.  The GT also adds on leather trim for the center console, shifter, and steering wheel.  The Sport Package is an option if you want performance tires, ground effects, and bright exhaust tips.  Heated leather seats, upgraded audio system, navigation system, a sunroof, flat-fold front passenger seat, and dual-zone climate control are other add-ons.  Owners praise the smooth ride, great power, and luxurious interior.  More headroom and better gas mileage top the wish list.
