by RM Sothebys | March 3, 2025

With an 83% sell-through rate, the February 27–28 auction kicked off ModaMiami in Coral Gables and also marked the culmination of the Indianapolis Motor Speedway Museum Collection.

• The 1966 Ford GT40 Mk II ($13.2M USD), 1908 Mercedes 150 HP Rennwagen ($8.25M USD), and 1957 Chevrolet Corvette SS XP-64 ($7.7M USD) led the sale.

• The auction achieved $74,491,720 in sales with an 83% sell-through rate overall.

• The last of the Indianapolis Motor Speedway Museum cars were offered on Thursday night, with all lots selling for a total of $34.4 million that evening alone.

• The 1966 Ford GT40 Mk II and 1996 Ferrari F50 both set new world records at auction.

RM Sotheby's returned to Miami for the third consecutive year, achieving $74,491,720 in auction sales at ModaMiami, the East Coast's premier luxury and lifestyle event. Held at the historic Biltmore Hotel in Coral Gables, Florida, on February 27-28, 2025, the auction featured over 80 cars, including rare models from the Indianapolis Motor Speedway Museum Collection.

The Indianapolis Motor Speedway Museum vehicles were showcased at premier auctions, including the Mercedes-Benz Museum in Stuttgart, and during Rétromobile Week in Paris. Proceeds from the sales benefited the Indianapolis Motor Speedway Museum, supporting the Museum's efforts to enhance and preserve its collection of Indianapolis 500 and Indianapolis Motor Speedway artifacts.
