Some of the most iconic muscle cars of all time had extremely limited production numbers and can sell for 6 figures or even 7 figures in some extreme cases. Many collectors are willing to pay such exorbitant price tags for outstanding condition vehicles with original factory parts and matching serial numbers because these models literally defined what many see as the greatest era of American muscle cars.
With that in mind, the American scene really started to take off with iconic muscle cars from the 1960s leading to what many would call the most iconic muscle cars ever made in the 1970s.

The R/T only options included a Rallye instrument cluster which consisted of a 150 MPH speedo, 8,000 rpm tach, and oil pressure gauge as well as the Shaker hood scoop.
There were less than 800 units produced with the Six Pack 440 engine and 727 TorqueFlite transmission, making it a collector's dream to find one in good original condition.

1969 Ford Mustang Boss 429 - 375 HP, 0-60 MPH In 7.1 Seconds
With less than 1400 units made of the 1969 Ford Mustang Boss 429, it is an extremely rare find today, with excellent condition examples selling for exorbitant prices at auction. The Boss 429 cu in V8 engine got built specifically to homologate for the NASCAR racing series, and as such had to be "dumbed down" to meet emissions standards.
With just a few mods such as a hotter cam, revised carburetor setup, and removing the restrictive smog pump, the 7.0-liter engine could easily increase output to upwards of 500 hp.
The potent Boss 429 engine came built to directly compete with the likes of the Mopar Hemi in NASCAR and found success with a total of 29 Grand National race wins. That performance combined with the aggressive body shape and stylish interior is why the 1969 Ford Mustang Boss 429 is an American institution.
