1970 Buick Skylarks equipped with Buick’s optional high-performance GSX package are already hard to come by, but the seller of this Saturn Yellow example claims it’s the only car of its kind in the world. Famed east coast tuning shop Motion Performance applied their handy work to the Buick’s engine and suspension system in the early 70s, making this already unique muscle car a complete anomaly.
An affluent Georgia Tech Student purchased this GSX when it was new and promptly drove it over to Motion, who performed various modifications to the car, making it a legend in the Georgia street racing scene at the time, the listing says. The car was sold and sat dormant for a long time before going under a complete restoration in 2006 which included stripping the car down to its bare metal to refinish the body and performing a “better-than-factory” alignment.
Some of Motion’s modifications include a Holley 3-barrel carb, aftermarket electronic fuel pumps, an Edelbrock B4B intake, Phase III ignition, Mickey Thompson Competition Headers, Motion valve covers and much more. The factory 455 V8 engine was also backed up with a modified Turbo Hydramatic 3-speed transmission, a 12-bolt Chevrolet rear-end with 4.10 gears and ‘Rally Ride Control’ suspension with Hurst shocks and yellow Lakewood ladder bars.
This well-documented GSX also comes with a summary of its history, a specs sheet, photos of the restoration process, a copy of its feature in Muscle Car Enthusiast magazine and a letter from the President of Motion Performance confirming its authenticity.
