The wheel arches are slightly squared off. The passenger cabin has plenty of glass area and thin window pillars. The quarter windows behind the passenger doors may not be the height of current fashion, but they make for great visibility. The Regal is a Buick, and Buicks have a tilt toward luxury. The Regal is no exception.
Interior materials are appropriate for the car, and imitation wood is tastefully absent.
Seats are leather-covered. The front buckets are soft, comfortable, and provide more lateral support than is immediately apparent. The driver's seat is electrically adjustable. The rear seat has room for three average-sized people. They are treated to both door and front seat back pockets.
