Evaluation: Rare enough as a GMC Sprint, but the factory 454 makes it even more special (most got a 350 or 400 cid engine). The rear bumper is a little beat up but the front is fine. Good paint, likely not original, with some chips at the back of the door edges and a few others throughout. Excellent unrestored interior. Original and aged but maintained underneath. Well kept, and good luck finding another one of these.
Bottom Line: Essentially an El Camino with GMC badges, the Sprint is a whole lot rarer than its Chevrolet cousin but it was only introduced in 1971, just in time for the end of the muscle car era. No matter, though. This is a pickup, after all, and with the GMC badging plus the factory 454 it would make a good conversation starter, not to mention a sweet tow vehicle for a vintage race car. This is a perfectly rational price for it.
