Overview
Collectible Motorcar is proud to offer this 55 years of single-family stewardship, this Arlington, Texas-built 1970 Chevelle Malibu Sport Coupe presents as a true SS-equipment, LS6-spec, 4-speed car that was dealer-warrantied with a replacement 454 LS6 shortly after new and then sold to its long-term owner in 1970. Finished from the factory in Gobi Beige (50) with black stripes and a Dark Gold vinyl roof (H), it retains hallmark SS details, benefits from careful mechanical refreshing in preparation for sale, and is accompanied by a partial build sheet, period magazines/brochures, a clean Montana title, and a set of 1970-dated LS6 cylinder heads included loose.

Rarity note: According to the LS6 Registry, only three LS6 Chevelles are recorded in Gobi Beige. Given this car's color/trim combo and equipment, it could be a unique (1-of-1) example within that extremely small subset. (Prospective buyers should perform their own due diligence with the registry.)

With only three Gobi Beige LS6 cars listed in the LS6 Registry, this example's combination of color, trim and equipment makes it a potential one-of-one opportunity for collectors seeking rarity with real road presence.
