The undisputed king of collector cars, the Mercedes-Benz 300 SLR Uhlenhaut Coupe remains the most expensive car ever sold. Named after Mercedes-Benz chief engineer Rudolf Uhlenhaut, only two examples were ever built, making it one of the rarest automobiles in existence.
The 1955 Mercedes-Benz 300 SLR Uhlenhaut Coupe is powered by a 3.0-litre straight-eight engine derived from the marque's championship-winning race cars. The Uhlenhaut Coupe was decades ahead of its time. When it sold for $143 million in a private RM Sotheby's auction, it didn't just break records; it completely redefined the collector car market.
