Wow, really? Thats interesting. Would love to know more. It seems there are 8 Cheetah's known to still exist. So they're very rare. One of them was turned into a roadster when still near new. This was Ralph Salyer's example, which had its doors blow off on the Daytona banking at 200mph due to unequal cockpit air pressure. Crew chief Gene Crowe solved that issue, plus the cockpit heat issue, by chopping the roof off.

There is a company that makes very accurate replicas and several of these have been constructed.
