The 1963 Buick Riviera Silver Arrow is a styling exercise done by Bill Mitchell for the Buick division to illustrate an upscale luxury coupe with some subtle custom touches. We found it at the 2013 Muscle Car and Corvette Nationals, and we were lucky enough to spend a few minutes with the car. Although the 2013 Muscle Car And Corvette Nationals has come and gone, you can visit this stunning car at the Sloan Museum.
