With its stiff suspension, heavy steering, and prominent exhaust sound, the Grand Prix presents a sporty veneer that comes up short in substance. The powertrain is responsive but lacks polish. Handling is secure but not agile. The interior is cramped for a car of this size. The rear seat, however, is short on head room, and the ride is unexceptional. Despite a redesign for 2004, the Grand Prix continues its mediocre tradition. The base V6 engine is fairly quick but noisy. The GTP model features a supercharged V6. The ride is very stiff and braking is only adequate. The low roofline limits head room and visibility.
