7. 1969 Ford Mustang Boss 429
The 1969 Mustang Boss 429 is a rare breed, built to homologate Ford’s powerful 429 V8 for NASCAR competition.
With only 859 units produced, its massive engine and aggressive stance set it apart from other Mustangs.
Collectors view the Boss 429 as a blue-chip investment, with values routinely exceeding $400,000 for well-preserved examples—often outpacing the Shelby GT350 and GT500 in today’s market.
Its motorsport heritage and exclusivity keep demand high in 2025.
