1970 Buick GSX
Offered by Mecum | Jefferson, North Carolina | June 5, 2020
“GS” is Buick-speak for something sporty. It’s been applied to Regals, Wildcats, and Rivieras. In 1966, the Skylark Gran Sport became its own sub-model in the Skylark line. It was broken out as its own model in 1967 in GS350 and GS400 form.
In 1970, Buick updated the model line to base or 445 forms, and it continued in this form through 1972. In the middle of 1970, Buick added the GSX performance package as a $1,196 option on the Gran Sport 455. Equipment included a hood tachometer, a four-speed Hurst shifter, and a 350 horsepower, 445ci (7.3-liter) V8. Only two colors were offered, and this one is finished in Saturn Yellow.
This was the top Buick of the muscle car era, and it debuted right at peak muscle car time. It was sort of downhill after this. In fact, in 1971, the GSX was just an appearance package. This example is one of two offered at this sale (the other one is white). You can see more about it here and see more from Mecum here.
Update: Sold $140,800.
