During Northern California’s annual Monterey Car Week, events like the Pebble Beach Concours d’Elegance, the Quail’s Motorsports Gathering, and racing at the Rolex Monterey Motorsports Reunion may be the major draws for most automotive enthusiasts, but for serious collectors, the real action is at the auctions. According to analysis from the team at Hagerty, specialists in classic-car insurance, Monterey’s five major auctions in 2023—presented by RM Sotheby’s, Gooding & Company, Bonhams, Mecum, and Broad Arrow—generated cumulative sales of $400.1 million with a 68 percent sell-through rate. That figure is down from the 2022 results of $473 million and a sell-through of 78 percent.

“While we began to see the top end of the market effected by inflation and higher interest rates for the first time, this year still marked the second highest total sales in [Monterey] car week history,” says Brian Rabold, Hagerty’s vice president of Automotive Intelligence. “We also saw the fifth highest public sale of a car in the Bonhams Ferrari 412P, and strong results for great examples of uncommon cars like the Honda NSX-R.”

Based on Hagerty’s ranking, the top lots that sold seem less a bellwether for the health of the collector-car market than a validation of the status quo when it comes to the most coveted automobiles out there. Here are the 10 most expensive cars to cross the auction block in Monterey this year.
