Details

GSX Historic Society documented as #543 of 678, this 1970 Buick GSX Stage 1 is a Concours Gold Award-winner that underwent a meticulous frame-off nut-and-bolt rotisserie restoration in 2010. After its completion it was a showpiece for Sloan Museum in Flint, MI. It has been well taken care of since. The panels line up well. The laser-straight body is finished in vibrant code-correct Saturn Yellow paint with a clear coat for a mirror-like shine. This GSX is powered by a GM AX-GS Stage 1 455ci engine that was completely rebuilt, paired to a TH400 automatic transmission. Out back is the G1 posi-traction 3.42 rear end. All of the L1 Soft Ray tinted glass is clear. The bumpers were rechromed. The bottom of the car is as clean as the top, with all tags intact everywhere they are supposed to be. The frame has been media-blasted and powder-coated. The interior features new hand-worked seats, carpet, L19 Gauges, Rally clock, hood tachometer and X2 Rally steering wheel. The factory-installed J3 seatbelts and Sonomatic radio with factory speaker system are correct, as is the dash, and the door panels have been reworked. It rides on a set of K7 wide oval tires wrapped around the original G60 15” chrome Rally wheels.
