This 1975 GMC Sierra Classic 3+3 is a rust-free survivor with only 25,652 original miles. Powered by a 454 big block and Turbo 400 transmission, this highly optioned truck features the Silverado package, Tiger wood grain trim, and factory A/C. It retains its original two-tone paint and a near-perfect original interior. Fully serviced with a rebuilt carb, new dual exhaust, and new tires, this low-mileage square body runs strong and is ready for the road.
