Check out this really rad doc directed by Tamir Moscovici about Magnus Walker. The rebel Porsche customizer who turned a hobby into an obsession, and an obsession into a successful business. "From a workshop in downtown Los Angeles, Magnus obsessively harvests fragments from donor 911s, grafting them onto vintage frames to create one-off automobiles with the spirit of Ferdinand Porsche but an ethos entirely his own." The documentary is about half an hour long so you might want to grab a popcorn. Enjoy.
