A $2.72 million sticker price puts the Mercedes-AMG One hypercar out of reach of all but the wealthiest car enthusiasts, but one Mercedes collector could have had 20 of them for the money he paid for a classic Benz racer last weekend.

The nonprofit museum partnered with Ontario-based RM Sothebys to sell some of its most valuable cars with the goal of raising $100 million for its endowment.

RM Sotheby’s held a standalone, single-vehicle auction to sell the 1954 Mercedes-Benz W196 R Stromlinienwagen at the Mercedes-Benz Museum in Stuttgart, Germany. The hammer fell at $53,017,370 (€51,155,000), making this the second-most expensive car ever to cross the auction block at a public sale.
