Buick Skylark (1970) for Sale in AZ

This 1970 Buick GSX is an ultra-rare, rotisserie-restored collector’s muscle car. Finished in the highly desirable Saturn Yellow with GSX-specific stripes and trim, this GSX is one of only 505 produced in 1970 and represents one of the finest examples of this iconic Buick muscle car ever offered. Powering the car is the original 455ci V8 paired with a 4-speed manual transmission—an exceptionally rare configuration for the GSX. The drivetrain is complemented by power disc brakes, a performance rear axle with positive traction (3.42 ratio), and the Rally Ride Control package for enhanced handling. The exterior features GSX-specific accents, including front and rear spoilers, GSX grille and panel emblems, color-coordinated racing mirrors, hood tachometer, and bold black GSX rocker panel stripes. Super wide white-lettered tires are mounted on chrome-plated wheels, completing the aggressive and authentic appearance. Inside, the car retains its original build sheet and owner’s manuals, featuring a console with bucket seats, rally-style steering wheel, full instrumentation including rally clock, and power windows. The interior is finished to a showroom standard that matches the exterior quality. With only 33,959 original miles, this GSX offers rare authenticity and drivability for collectors seeking a top-tier example.
