The 2003 Buick Regal is a part of the brand's fifth-generation midsize sedan lineup. Two trims are available in this year - the LS and the GS. The Regal LS hosts a standard 3.8L V6 engine with 200 horsepower, while the sportier GS model features the same engine but with a supercharger, cranking up the power to 240 horsepower, both paired with a 4-speed automatic transmission. Key safety features include anti-lock brakes, dual front airbags, and traction control. Inside, Buick offers a tilt steering wheel, power windows/locks/mirrors, cruise control, and a CD stereo as standard amenities. The GS trim goes a step further, featuring automatic climate control, a power driver’s seat, and a leather interior. Despite being a 2003 model, it offers quite a comfortable and quiet ride.
