19. 1971 Ford Mustang Boss 351
Made for one year only, the 1971 Mustang Boss 351 was one of the rarest Mustangs Ford ever produced with only 1,800 made. A highly-tuned version of the 351 V8 engine with around 330 HP powered it. It was fast, good-looking, and more expensive than the Mach 1 version of the same model year. Today, it’s a true collector’s item.

Also, this was one of the quickest muscle cars of the time as well as one of the quickest Mustangs ever. The powerful 351 V8 managed to launch the Boss 351 to 60 mph in 5.8 seconds, which was and still is quite fast for an analog muscle car from the early 1970s.
