History is priceless only if no one can afford it or it’s not for sale. The first publicly-available 1954 Mercedes-Benz W196 R Stromlinienwagen sold for $53.9 million at auction on Saturday after spending decades in the hands of the Indianapolis Motor Speedway Museum.

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.
