RM Sotheby’s kicked off its 2022 live auction calendar last week with the company’s 23rd annual Arizona sale hosted by the plush Arizona Biltmore in Phoenix. The one-day auction garnered $43.3 million in sales, with 95 percent of all lots sold and registered bidders from 30 different countries.

An impressive 24 percent of all registered bidders were first-time clients, showcasing the continued growth of the industry.

Establishing a record price for the model offered publicly at auction, a 1955 Mercedes-Benz 300 SL Alloy Gullwing sold for an incredible $6.8 million as the undisputed star of the sale. This particular car was one of very few to retain its numbers-matching 3.0-liter NSL engine and original alloy body.

A 1931 Duesenberg Model J Tourster, one of the most iconic of all American cars of its era, drew crowds during preview days. Boasting magnificent original coachwork, this CCCA Full Classic had received a meticulous restoration by RM Auto Restoration, retained all its original components, and sold for an outstanding $3.4 million, exceeding its pre-sale high estimate.
