It typically offers a length in the upper-middle range (around 4.9 meters), with comparable width and height figures contributing to a spacious cabin. Luggage capacity is also similar or slightly better than some rivals, making the Regal III practical and comfortable among its class. Its size balances sporty appeal and usability for the average coupe buyer of that period.

While specific interior dimensions vary slightly by trim and model year, the Buick Regal III Coupe is noted for its relatively spacious cabin for a two-door coupe.

Its design provided comfortable seating for four passengers and a driver, making it a practical choice for those who needed a stylish coupe without sacrificing passenger convenience.

The turbocharged V6 versions were particularly popular for delivering brisk acceleration and sporty performance characteristics. Engine sizes typically ranged from a 3.0-liter V6 to a 3.8-liter V6. The performance balance these powertrains offered complemented the size and weight of the car, catering to drivers seeking an engaging yet refined coupe.
