The pictures on the top in that link are from the Auto Design magazine. There were 7-8 designs proposed by Pininfarina (many of them by Ken Okuyama), and they picked the design what is the Enzo now. Ken did an amazing job designing the car. He is a great designer, who also did Ferrari 612, Maserati Quattroporte, and Pininfarina/Ferrari Rossa prototype. Here are some pictures (middle of the page) of Ken Okuyama checking out a Ferrari Enzo at my friend's garage in Malibu. It was great to have Ken, the designer of the Enzo, and a brand-new Ferrari Enzo in one place. http://www.patrickshim.com/PatrickShim_Personal_AutoSocial.htm
