Ford Mustang Boss 429 – $605,000
Getting 605 thousand dollars for any car is a fantastic achievement, let alone for Boss 429. Despite its rarity and mystic allure, the Boss 429 never achieved such a high amount. This number is a record for Boss 429 cars, and a particular example had a NASCAR engine with special Ford C9AE-A heavy-duty half-inch bolt rods, forged pistons, and steel crank, among many other factory options. Of course, it was perfectly restored and well-documented.
