24. 1965 Chevrolet Chevelle Z16 – $250,000+
What exactly is the Chevelle Z16? Basically, it’s a regular Chevelle with several added speed options. Powered by 396 V8 engine with Muncie 4-speed gearbox, and heavy-duty suspension and equipment. Some dealers weren’t aware that this option even existed and Chevrolet refused to market the Z16 for some reason, making it a kind of secret model (via Motor Trend).
The Z16 was pretty fast, but it was also expensive for a Chevrolet. The company made only 200 of them as a result. This muscle car is the 1965 model year only. Most of the dealers didn’t even have the idea that Chevrolet built it, making it a rare item for collectors of today because it is so scarce.
