The restoration was done by Tim Mings, who specializes in restoring N600s and their sportier looking siblings, the Z600s. He performed a ground-up restoration, from the interior to the car's 600-cc, 9000-rpm, two-cylinder engine. Now that it's finished and has made its debut at the Japanese Classic Car Show in California, it will head off to the company's museum.
