It's easy to forget how popular the Mustang II was when it was introduced, with more than 385,000 units produced. By 1975 the 302 V-8 engine was available. The car could be had with either a formal roofline or as a fastback. A convertible version was not offered. This '76 version has both the slick roofline and the V-8 engine. The late-model Mustang wheels make for a good-looking modification.
