Urban Outlaw is the wonderful portrait of Magnus Walker, “the rebel Porsche customiser who turned a hobby into an obsession, and an obsession into a successful business.” Ever since a trip to a London motor show aged 10, Walker has grown obsessed over Porsches, now grafting obsessively harvested fragments from donor 911s onto vintage frames to create wonderful one-off automobiles with the spirit of Porsche but an ethos entirely of his own.
