After buying a model 300zx off of ebay and reading the description of the car there was one sentence that stood out. "The elegant and aerodynamically functional body styling is the result of hundreds of hours of wind tunnel testing, which produced a drag coefficient od Cd. 0.31, one of the lowest figures of any car on the road today!" I thought that was a cool piece of info, not only made the car sound awesome but very well designed as well!
