Available as a sedan or coupe, the 1999 Pontiac Grand Prix is a roomy mid-sized car perfect for family trips, while its high-performance V6 engine and sporty handling have enough kick to keep the driving enthusiast plenty satisfied.  
Sedans come in SE, GT, and GTP trims.  Coupes come as a GT or GTP only.  The SE features a 3.1-liter, 160-hp V6, while the GT and GTP come with a much more aggressive and faster 3.8 V6.  In the GT, this hits 200-hp, a 5-hp increase from the previous year.  The supercharged GTP achieves 240-hp.  This engine is an option on the SE sedan.  A 4-speed automatic is the only transmission, though it does come with normal and performance shift modes.  Other new additions to the 1999 Grand Prix are a few more options, including heated seats and OnStar.  The GT sedan and coupe get a standard rear spoiler to help create a sporty look to go along with its engine.  
A wide track design and stiffer suspension mean better handling for the 1999 Grand Prix, and drivers notice this right away.  They say it performs best on the highway, has great acceleration and engine power, and takes curves and corners easily and tightly for a mid-size car.  It is also sturdy and good in bad weather.  Other favorite features are the pass-through to the trunk, the heads-up display, and the increased roominess.  Cheap-looking and easily broken plastic parts are annoying, as is a tendency to squeak and rattle.  Drivers wish there was a manual transmission option.  Problems with the power window regulators persist.
