Mayweather claims a Las Vegas dealer bought the rare G650 for $728,000. However, he’s found himself locked in a bitter legal dispute with a car dealership in Las Vegas, where he claims he was charged far too much for one especially rare Mercedes-Maybach. However, Mayweather quickly reneged on the deal, returning the Ferrari, Porsche, and McLaren. Accusations Over PriceAccording to a newly filed lawsuit, Mayweather is accusing the dealership of deceptive trade practices and misrepresentation. Mayweather says he was led to believe the dealer had paid $1.1 million for the car, a margin he was willing to accept, but later learned otherwise.
