Buick released the Sport Wagon as a long-wheelbase version of the standard Skylark station wagon. With that wheelbase came optional third-row seating and a raised roof with skylights so the entire family could enjoy the view. While the Sportwagon might not be the prototypical muscle car, there's not much cooler than a fast wagon which is why our A-Body LS Swap systems are a perfect fit.
