A super-rare 1968 Buick GS 400 Convertible—one of just 2,454 made—is hitting Hagerty Marketplace with no reserve! This beauty’s got a four-speed manual, fresh upgrades, and even a spot on the 2025 Hot Rod Power Tour. Restored in its original Ivory Gold Mist, it’s got modern touches like Flowmaster mufflers and a power top. If you’re into muscle cars with both history and road-trip cred, this is the one everyone’s talking about! #MuscleCar #BuickGS400 #CarAuction #Cars #BuyingCar
