Buick’s GS or Gran Sport tag was initially applied to the automaker’s Skylark model in the Sixties, before extending to cover hot variants of the Riviera, Wildcat and Century. Choosing a GS Buick meant that you were availing yourself to some pretty impressive and giant-killing performance. Here, we’ve got a 1966 Buick Skylark GS for sale from what better place than Indianapolis! With 2,600 miles since some comprehensive work, this beast comes with a 494ci V8, a T-56 6-speed manual box, a new black interior and many more things to make this Skylark soar like an eagle.
Exterior and Interior
This 1966 Buick Skylark GS comes repainted in black because what better shade for a sinister car than the most sinister color in the world. With its quad headlamps, handmade hood aqueducts and 3-inch exhaust hooked up to a Flowmaster H-pipe, this car looks every bit as menacing as it sounds, and goes. It’s got the requisite chrome bumpers, Skylark and GS badging, but swaps original wheels for a set of aftermarket five-spoke units. The wheels aren’t just for show, they’re need to accommodate the wider tires and bigger brakes! The black interior of this 1966 Buick Skylark GS features black leather seating for four adults, plenty of white-faced aftermarket gauges, and a push-button radio. Look closer and you’ll see an aftermarket heating and air conditioning unit, some aftermarket speakers and a nice white-topped gear shift knob. Yup, this car is full of surprises and yet it’s acceptably comfortable to be used for regular driving if you desire.
Engine
A 494ci V8 powers this 1966 Buick Skylark GS, paired with a Buick T-56 6-speed manual transmission. Power goes to the rear wheels through a Ford 9-inch rear end. The engine inhales through dual 4-barrel carbs, and expels spent gases with suitably veracity via big tube headers, a new 3-inch exhaust system and a Flowmaster H-pipe. You’ve also got TA aluminum heads, MSD ignition, Eagle H-beam rods and J&E forged pistons. Elsewhere, there’s four-wheel disc brakes to suitably rein in the upgraded power – because like the old Pirelli slogan, power is nothing without control. And in control you must be, with this car!
Inspection
1970 marked an important year for Buick’s midsize muscle car lineup, as the Skylark 350 Sport Coupe blended the brand’s signature comfort with increasingly aggressive performance styling. While Buick’s GS models often stole the spotlight, well-optioned Skylarks like this example have become increasingly appreciated for offering the same muscular A-body proportions and V8-powered driving experience at a more approachable level. Showing approximately 19,245 miles on the odometer, this Skylark benefits from a substantial refurbishment and modernization effort that included drivetrain work, suspension upgrades, steering enhancements, interior refresh, and cosmetic refinishing. Finished in Bamboo Cream over a Saddle vinyl interior, this Buick stands out with tasteful GS Stage 1-inspired styling cues, upgraded handling components, and classic American muscle car presence.

This 1957 Buick Roadmaster Riviera 2-Door Hardtop is pure late-1950s American excess in the best possible way, combining dramatic Harley Earl-era styling with the torque-rich character of Buick’s Nailhead V8. Showing approximately 14,574 miles, this example was refurbished in the late 2000s and is finished in Dover White and Bittersweet Red over a Rust and Ivory interior. The car was later upgraded with an Air Lift Performance air suspension system. Add in power steering, power brakes, power windows, a power front bench seat, Hot Rod Air climate control, and wide whitewalls, and this Roadmaster delivers the extravagant look of a flagship ’50s Buick with a few thoughtful upgrades that make it even more enjoyable today.
