The original Ford Mustang debuted in 1964 at a price of $2,368 and was an immediate success, receiving over 22,000 orders on the first day. Mustang sales reached an astounding 417,000 units in the first 12 months. Throughout the 1960s and early 1970s, the Mustang established itself as an American automotive icon and muscle car, offering high-performance variants like the Shelby GT350 and Boss 302. However, in response to rising fuel costs and emissions standards in the 1970s, the Mustang moved to smaller, more efficient designs before resuming its performance roots in the 1980s and beyond.
