The body structure is stiffer and the engine is mounted on a separate cradle that is isolated from the body with rubber mounts. With the GS Buick has created a sports sedan that is long on subtlety and short on flashiness, a sports sedan for the mature adult who doesn't want to flaunt its performance. Inside, the light-gray leather seats, with optional heating units, not only looked inviting but were comfortable places to spend some time. Buick prides itself on the quality of its seats, and it is doing a good job in that area. The bucket seats have side padding for support, yet they are not so contoured as to be restrictive.
Seams run vertically so as to be less bothersome to occupants.
In back, the longer wheelbase results in greater kneeroom. The seat tracks that have greater fore and aft travel and the backs of the front seats are sculpted to give more legroom. Carrying skis or other long objects is accommodated by a lockable pass-through to the trunk. An integrated child seat is available. Like the Grand Prix, the angle of the rear seat back is pronounced, and some folks will find it uncomfortable on long trips.
