5. Ford Mustang Boss 429: $605,000
Getting $605,000 for any car is an amazing achievement, let alone for the Boss 429. Despite its rarity and mystic allure, the Boss 429 never commanded such a high amount. The previous record was $550,000 for the 1,000-mile Mustang featured second on this list, but this is significantly more money. So, what makes this red example more desirable and ultimately more expensive?
This is one of the first Mustangs they made by hand. It featured an 820-S NASCAR engine with special Ford C9AE-A heavy-duty half-inch bolt rods. It also had forged pistons and a steel crank, among many other factory options. Ford hoped that NASCAR would accept the Mustang, so the first examples were more specific. They featured equipment and an engine with slightly more power and race-specific components.
Besides all of that, the best-known and respected names in the Mustang world restored this Boss 429. So, the price was high yet justified by the providence of this car.
