Photographer Max Siedentopf is a serial guerilla car pimper. He prowls the streets of Amsterdam and then picks random stranger’s cars that he “upgrades”.

He explains his strange obsession to Vice: “Individuality, self-expression and status are more important than ever these days. But for some reason you see that things as ordinary as cars are getting personalized less and less, while it could be a strange but great form of self-expression. I thought I’d do people a favor by giving them a custom-made supercar.”
