Cazoo is an online used car dealer that has burst onto the motor trade scene amid a blitz of publicity, cash and controversy.In this special Car Dealer Investigation we take a closer look at the people behind the self-titled 'online used car disruptor'. We investigate where the billions have come from to launch the business, discuss whether the huge sponsorship deals across the sporting world have been worth it – and take a look at why shares have plummeted since the firm listed on the New York Stock Exchange in 2021. We chat to car dealers about Cazoo founder Alex Chesterman's cutting comments about the existing motor trade and ask the experts which disruptor they think should worry the motor trade the most. And, finally, we try to answer the big question: Will Cazoo will ever really become the dominant dealer in the used car market?
