2003 Pontiac Grand Prix Overview

The stylishly sleek coupes are no longer in the lineup for the 2003 Pontiac Grand Prix. Now it only comes in a more family-oriented 4-door sedan, as a base SE, GT, or supercharged GTP. More full-sized than its mid-sized classification, the Grand Prix always aimed to blend heavily-loaded luxury features with a dash of exciting driving performance.
Engines remain the same for each trim. A 3.1-liter, 175-hp V6 powers the SE, and a 3.8-liter, 200-hp V6 propels the GT. A supercharged 240-hp version of the 3.8 sits in the sportier GTP. All are matched with a 4-speed automatic overdrive transmission, with normal and performance modes. Additional changes to the 2003 Grand Prix include more across-the-line standard features, such as a CD player, overhead console, backseat reading lights, and the trunk pass-through. A Limited Edition Package for the GT and GTP again gives them a new spoiler, badging, white gauges, blue foglights, and seats with leather inserts to keep you from moving around when chasing curves.

Performance-wise, 2003 Grand Prix owners seem very happy. They love the engine power, great pick-up, easy cruising capability, and the stability and confidence of the wide track handling. The Grand Prix looks and feels sporty enough for parents who don't want to entirely sacrifice fun for responsibility. Seating room is spacious and gas mileage decent. The heads-up display remains a favorite feature. A sloping roofline limits rear headroom, say owners, the thinly padded seats are not comfortable for long trips. Once again, a shoddy-looking plastic interior suffers from rattling and is not durable. Some drivers report a noisy ride.
