18. 1969 Ford Mustang Boss 429

Current Value: $180,000 Original Price: $4,798 The majority of us already have a solid understanding of the term "mustang." Ford introduced the iconic model in 1964, and it became popular right away. The 1969 Boss 429 featured the same features that Ford buyers knew and liked, but with a twist. It was back and better than ever a short time later.

The updated variant, which boasted 375 HP, was made to rival Chrysler's 426 Hemi. That is precisely what it did. Ford went above and beyond to make the first Mustang to ever have a rear sway bar as reliable as possible. Moreover, less than 1,000 of them were ever produced. Take this one as a treasure.
