The 1500 itself was produced 1962-64, but variants continued to be built until 1977. Its styling is an an extension of that of the BMW 700 (introduced 1959), an early example of the "three-box" look popular into the 1980s that was abandoned due to the need for better aerodynamic efficiency. The look's features included a squared-off, boxy appearance that usually included a tall "greenhouse" with large windows that had the effect of making the car seem less heavy than it otherwise would have appeared. BMW's styling director at the time was Wilhelm Hofmeister. Consultation was provided by the prolific Italian stylist Giovanni Michelotti.

All told, the 1500s styling was a great success. The car was fairly small, and the airy greenhouse emphasized lightness. Unlike garish, baroque styling found on late 1950s American cars, the 1500 was plain, with little ornamentation other than in the grille area. As mentioned, the main defect was the secondary side character line that might have been necessary for sheet metal stiffness, but was poorly placed.
