13. Chevrolet Chevelle Z16
You may be wondering exactly what the Chevelle Z16 is. Basically, it’s a fully-loaded regular Chevelle with all the necessary options. They include a 396 V8 engine with a Muncie four-speed gearbox and a heavy-duty suspension and equipment.

Yet even some Chevy dealers weren’t aware this option existed. In fact, Chevrolet refused to market the Z16 for some reason. That made this Chevelle kind of a secret model. The Z16 was fast, but it was also expensive for a Chevrolet, so they made only 200 of them.
