An estate sale, a numbers-matching V8 sitting on a stand in a garage, and a certified appraiser willing to put a hard number on all of it — that’s the setup behind this 1968 Buick GS 400 out of Port Huron, Michigan. AutoAppraise’s Jason Phillips values the car at $35,000 after tallying over $20,000 in documented drivetrain work alone, but it’s the low, bellowing idle that keeps pulling viewers back years later. Is a scarce, correctly-matched GS400 actually the smartest buy in 1968 muscle?
