Check this out... think I'll build one someday

Not to hijack this thread, but Jim Halls Chapparal race cars are now housed at the Permian Basin oil museum in their dedicated wing. He had been approached by the smithsonian about them, however he wants them maintained in running condition, and said they belong here in Texas. On nice days his cars are regularly started up and driven outside to be parked in front of the museum.

Mr. Hall made his money as an oil geologist, but was a college study in applied aerodynamics, and used this to his advantage designing race cars. I believe he even had his own small scale wind tunnel for testing his ideas as well.
