Buick may have marketed it a sport luxury coupe, but the body style and interior configuration with the large parcel shelf in the back and the two storage containers scream business Coupe.
As the owner of an 89 red/saddle with the same mileage as yours I must say you've done this car a great disservice with the video review. Reattas must be photographed from waist level or below. Using a wide-angle close-up from a high viewpoint as shown robs the car of its graceful sleekness and makes it look like a stubby econobox. The Reattas are great cars. A little respect please.
