Nakai-san who founded the 80-90's street racing team "Rough World" (that then changed to his company name with a german twist, at the same time he switched his ownership from a AE86 to a 930) has been building unique cars for nearly 20 years. Porsches and Truenos/Levins have been his own favourite since the 80's.
His designs are throwbacks to the glory days of the 1970's Porsche Group 4 GT. Love or hate his designs, they are EFFECTIVE, and they do get track results as much as they get head turns in the streets.
i didn't know that 70's and 80's Porsches that were built for the track will end up "outdated" in a few years. Clearly if a car still stands up in a crowd after 40 years, it won't ever be outdated.
911 = Purest Sports Car ever built.... PERIOD.
