Yes, I know it’s an endless point of debate, but let’s face it, the original (1963-1965) Riviera is the greatest of them all. It was an absolute styling sensation when it arrived, arguably the best-styled American car not just of the sixties but even the whole post-war era. And it wasn’t just a pretty face; its performance was outstanding, and not just in a straight line. The Riviera was a world class gran turismo.
In 1965, Buick upped the ante with the Riviera Gran Sport. Standard equipment was the ultimate 360 hp dual-quad “nailhead” 425 Super Wildcat V8, a reduced backpressure oversize dual exhaust system, a 3.42:1 Positraction rear axle and a few other goodies. CARS magazine wrung one out and was duly impressed.
