A V6 Supercharged car that eats V8's for lunch, especially Mustangs.
My GTP just smoked another 5.0 Rustang!

Get the Grand Prix GTP mug.
The GTP is Pontiac Grand Prix with some performance extras: a supercharger, upgraded suspension and brakes, etc. A "sleeper" - a car that looks slow, but is not. Don't get me wrong - it is not a real sports car, but more of a sports sedan. You get V8 power, and V6 fuel economy. Also, this car has a good deal of modding potential.
1997 - 2003 Pontiac Grand Prix GTP - Stock 3.8L V6: 240 horsepower, 280 ft.lbs of torque. 0 - 60: about 6.6 seconds - not too bad. Fuel economy: around 18 city, 28 highway - not too bad either. 1/4 mile: around 15 seconds - again, not bad.

The usual compromise that is made when a husband (who wants a sports car) and a wife (who wants a grocery getter) buy a car together. It's a good looking car, and decently fast-certainly faster than 90% of the stuff she could have goaded you into buying if she loved you less-but contrary to what people will tell you, it will never outperform a pony car, and even a V6 Mustang will eat it for lunch.
I went and did a 15 on the drag strip in my Grand Prix GTP while I had 30 pounds worth of groceries in the car! Rock on!

An overweight family truckster that rednecks think of as a muscle car.

Discontinued due to poor sales, replaced by the Pontiac GTO.
Dude, did you see that minivan pass us? You should feed those gerbils under the hood more often!
