North London residential borough Enfield might have seen just as many over-the-top supercars as the Gumball 3000. That's because it is where celebrity car customizer Yianni Charalambous runs his garage, Yiannimize.

Yianni specializes in incredibly rare and expensive cars. Ferrari, Aston Martin, Porsche, McLaren, Bentley, Rolls Royce, he's wrapped them all. Among some of the celebrities Yianni has worked with are KSI, Harry Styles, Rupert Grint, Gordon Ramsay, and Anthony Joshua.

"I'd like to think that I'm one of the pioneers because I got into this industry very, very early," he told Business Insider. "My client base is celebrities, but it is high-net-worth individuals. It's not easy to get that client base. For them to work with you, one, you need to be pricing them correctly and, two, they need to trust you. Trust is key in this industry."

Yianni posts regular updates from his garage on his YouTube channel, which has over 1.2 million subscribers. Watch the video to see some of the incredible cars he wrapped, as well as finding out how wrapping works.
