Remember those exceedingly wealthy people that populate the majority of the Gumball 3000 that we've been telling you about all week? Today we bring you another one of them. Sitting atop the Gumball pack, we found this Mercedes-Benz SLR McLaren Stirling Moss shinin' under the brief London sun. We thought it was a prop car until we found the dude who was going to be driving it: Marcus. For those that don't know, the Mercedes-Benz SLR McLaren Stirling Moss was produced as a tribute to Sir Moss, one of the best race-car drivers ever. Only 75 were built and each was priced around $1 million. So how did this guy come across one of the most rare Benzs ever made? He won't say. Read what he did say and check out more photos of his ride below.
