17: 1969 Ford Mustang Boss 429
In terms of the Mustang, Ford has always managed to refresh the brand. When the Camaro was phased out of production in 2002, it was because the car had become stale. Ford is constantly adding special editions to the Mustang such as the Mach-1, the Boss 429, and even the Cobra. The Mustang lineup is constantly kept in rotation so that consumers don’t get bored. The 1969 Ford Mustang Boss 429 is among the rarest Mustangs to ever go into production.

You’ll rarely see one of these sell at auction for values less than $200,000. The sheer design of the car looks like a beefed-up muscle car. Ford put a high-stakes design on the table for the 1969 Ford Mustang Boss 429 and it paid off. Everything about the Boss 429 is unique, from the enormous engine bay to the high-performance design. Values will continue to rise.
