RM Sotheby’s hasn’t given an estimate for the original Type 64, which established much of Porsche’s historic engineering and design right up through the 911. Considering this may be the only opportunity to buy such a historic Porsche—at least for a long while—its hammer price is anyone’s guess. Don’t be surprised if it comes close to (or even surpasses) the record held by the 1970 Porsche 917K used in the Steve McQueen movie Le Mans, which sold for $14.08M at Gooding’s 2017 Pebble Beach auction.
