RM Sotheby's is inarguably the leading classic car and automobilia auction house for selling collections at auction. We have sold more than $152 million in collections in the last three years and have sold more collections above estimate than any other auction house, in addition to having the number one sell-through rate.

Over the years, many important collectors and estates have chosen to sell their automotive assets with RM Sotheby's – whether at a bespoke single private collection sale hosted at the location where the collection resides, or at a single-segment sale where the assets are brought to auction and sold within one of our calendar auctions.

RM's experienced and skilled staff are capable of handling all aspects of every sale, from pre-sale preparation and conditioning to careful cataloguing and stunning photography. What would otherwise be a difficult and time-consuming task becomes a simple and efficient process that maximizes the proceeds where it counts – in the final price at auction.

With our international network of buyers and our track record of sales surpassing a collection's high estimate, the choice to take advantage of RM's industry-leading marketing and unsurpassed services—whether as a private collection sale or a single-segment sale—has never made more sense.


The Guyton Collection

Pre-Sale Estimate: $8.9M   |   Total Sold: $11.7M   |   Sell-Through Rate: 100%
The esteemed Guyton Collection, comprised of 73 automobiles and hundreds of lots of automobilia of the late Mr. Fred Guyton, offered entirely without reserve. The 4-5 May auction, was RM Sotheby’s 34th private collection at auction and drew strong bidding activity from more than 27 countries around the world, with more than 40 percent of bidders representing first-time RM Sotheby’s clientele. A renowned architect and active member of the St. Louis community, Mr. Guyton was also a treasured and respected figure within collecting and car club circles, having amassed his collection over more than four decades. The sale featured historic American and European motor cars from the Veteran, Brass and Classic Eras – many of which had been in the collection for decades. Well over 500 pieces of automobilia, collectibles, petroliana, sports memorabilia, and original artwork were auctioned, alongside more than 3,000 model and toy cars, including what was regarded as one of the world’s finest assortments of Minic Clockwork Toy Cars.

The Dingman Collection

Pre-Sale Estimate: $5.1M   |   Total Sold: $7.0M   |   Sell-Through Rate: 100%
The Dingman Collection, offered entirely without reserve, comprised the remarkable cars and collectibles of the late Mr. Michael Dingman. This third and final auction, which succeeded earlier auctions in 2006 and 2012, was likewise a resounding success with record bidder registration and final results that far exceeded the catalogue estimates. Certainly, the desire to acquire a valued piece from Mr. Dingman's collection was a strong contributing factor, as was the collection's reputation for quality. Finally, however, it was RM Sotheby's ability to bring bidders to the table who were exclusively car collectors at a very high price point, which contributed to the record sales, as these individuals bid concurrently and very competitively against the pre-existing "sign-buyers".
