This 1955 Austin-Healey 100 BN1 boasts a 60-year racing history with the seller's family, including SCCA championships, and features extensive modifications like a 2.7-liter inline-four with an aluminum head, Muncie M3 four-speed, Ford 9" rear end, and four-wheel disc brakes. The car has widened bodywork, a roll bar, and aftermarket 15" alloy wheels, though it shows signs of past repairs, rust, and engine leaks. It was previously featured on BaT in 2017.
