Buy Nissan Skyline GT-R:
Most Skylines in America ultimately come from Motorex in Torrance, California. Nissan never exported any Skylines to the United States, so a few had to be sacrificed to prove their crashworthiness to the Department of Transportation (DOT), and it’s Motorex that did that testing. It’s been applying what it’s learned to producing DOT-approved Skyline GT-Rs ever since and has put somewhere between 170 and 180 on America’s roads, says General Manager Quincy Yamada.

The conversion process is straightforward, explains Sean Morris, who used to work for Motorex before opening his own shop, RB Motoring specializing in Skylines. “The biggest thing was proving to the DOT that they were crashworthy,” he says. Getting the car’s emissions in line takes some work, but it’s doable. Then there are dozens of details like making sure all the labels and identification numbers on the car conform to standards that go into making a car strictly legal.
