RM Sotheby's

RM Sotheby's is a collector car auction company headquartered in Blenheim, Ontario, Canada, with offices across the United States, Europe, and the Middle East. The company specializes in the sale of classic, vintage, sports, and exotic cars, and is responsible for the sale of seven of the top ten most expensive cars ever sold at auction. Included in this is the sale of the 1955 Mercedes-Benz 300 SLR 'Uhlenhaut Coupé', sold for 135 million Euros in May 2022, the most expensive car ever sold and one of the most valuable objects ever sold at auction. The previous record for the most expensive car at auction, a 1962 Ferrari 250 GTO, had also been sold by RM Sotheby’s, at their 2018 Monterey auction. RM Sotheby’s services include auctions (online and in-person), private treaty sales, financial services, valuations, and estate planning, and they have been partly owned by Sotheby's, a global auction house dealing in fine art, since 2015.
