The Buick Regal is a 4-door sedan that was manufactured from 1973 through 2004. Originally designed as a luxury coupe, changes over the years repositioned the vehicle as a mid-level family car. The vehicle went through four generations of body styles, with the final Buick Regal design debuting for the 1997 model year. Situated in the mid-size sedan class, the Buick Regal competed for market share with such vehicles as the Honda Accord, Toyota Camry and Ford Taurus.

Buick Regal Styling

The fourth and final generation of the Buick Regal was slightly larger than the previous design. Overall dimensions include a length of 196.2 inches, width of 72.7 inches and height of 56.6 inches. The vehicle shared numerous similarities with another mid-size stable mate, the Buick Century. Both sedans were built on the W-body platform, which was also used on GM vehicles such as the Chevrolet Impala, Chevrolet Lumina, Chevrolet Monte Carlo, Oldsmobile Cutlass Supreme, Oldsmobile Intrigue and Pontiac Grand Prix.

The Regal was longer than the Buick Century and marketed as a sportier, more upscale mid-size option. Inside, the vehicle's roomy interior made the Regal a popular choice for American families. User-friendly controls and gauges made driving the Regal a straightforward endeavor. Fake wood accents were intended to give the interior of the vehicle a touch of class.

The upscale GS model offered such upgrades as dual climate control, leather seats and a trip computer.
