A 1955 Mercedes-Benz was auctioned off for around $143 million at the Mercedes Benz Museum in Germany, making it the most expensive car ever sold. The Mercedes-Benz 300 SLR Uhlenhaut Coupe is one of only two prototypes made by the racing department of Mercedes-Benz. The sale puts the coupe on the list of one of the most expensive items ever to be sold in an auction. The money from the sale will be used to establish the Mercedes-Benz Fund that will provide scholarships in the fields of environmental science and decarbonisation.
