Stepping into a 1966 Buick Riviera meant entering a world of luxury and performance. The standard offering wasn’t a slouch, boasting a 425 cubic inch V8 engine churning out 340 horsepower. This was enough muscle for most drivers who craved a smooth and powerful ride. But for those who desired a more exhilarating experience, Buick offered the Gran Sport (GS) package.
Upgrading to the GS transformed the Riviera into a corner-carving machine. This package included a heavy-duty suspension system that hugged the road tighter, bucket seats that provided superior lateral support during spirited driving, and a limited-slip rear axle that enhanced traction and agility.
However, the crown jewel in the Riviera’s performance lineup arrived courtesy of the elusive Super Wildcat package. This dealer-installed option wasn’t just about aesthetics it was a true powerhouse. By equipping the 425 V8 engine with a dual four-barrel carburetor setup, Buick engineers unleashed an impressive 360 horsepower.
This surge in power transformed the Riviera from a luxurious cruiser into a muscle car with a serious bite. The exclusivity factor further heightened the Super Wildcat’s allure. In 1966, only 179 Riviera GS models rolled off the production line equipped with this coveted package, making them incredibly rare and valuable collector’s items today.
This impeccably preserved Buick Riviera GS exudes a sense of having been cherished throughout its life. Years spent tucked away in a garage have undoubtedly contributed to its phenomenal condition, but there’s another key factor to its enduring appeal.
A professional repaint, meticulously replicating the car’s original Shadow Turquoise finish, now gleams with an unmatched vibrancy. While a personal inspection or third-party verification is always recommended, photos simply cannot capture the car’s true brilliance.
Thankfully, the original charm extends to the interior, which remains untouched. Under the hood, the numbers-matching engine continues to deliver classic Buick performance, further enhanced by a rebuilt original transmission. This combination promises a truly exhilarating driving experience.
The seller’s asking price strikes a balance between fairness and value, and the enticing “Make Offer” option adds another layer of flexibility. This one-owner Riviera GS, a true automotive gem, is unlikely to remain available for long.
Currently residing in Arizona, this beauty appears more than capable of tackling a cross-country journey. With the listing set to expire in about a month, you have ample time to not only arrange a viewing but also to make a compelling case to that special someone that this immaculate GS Super Wildcat deserves a place of honor in your garage.
