Just like the original Mustang, the Mustang II was the right idea at the right time. They sold quite well in their first few years due to the gas crisis / manipulation by OPEC. People were dumping traditional musclecars left and right for low prices. Later, Iacocca had another great idea with the Chrysler minivan. The Mustang II performance models like the Cobra with lots of tape stripes, and another one I recall that had a big spider on the hood (?) were a bit overdone, There just weren't many genuine factory performance cars at the time. For example, you could still get a Pontiac Trans Am with a 455 under the hood in '76, but it was essentially the same engine from a station wagon. Low mpg, along with low hp and torque numbers.
