Millions upon millions of dollar flew all over the place over the weekend during the Mecum auction at the Pebble Beach Concours d’Elegance. A 1956 Aston Martin DBR1 had top billing when it sold for a whopping $22.5 million, becoming the most expensive British car in history. A collection of road-going Ferraris combined for $16.5 million, including a 1961 Ferrari 250 GT SWB that sold for $8.3 million. Even Floyd Mayweather Jr.’s 2010 Koenigsegg CCXR Trevita found a new owner who paid a cool $2.8 million for it. Lost in all the hoopla surrounding the auction were four vehicles that look the part of classics from yesteryear, but are actually miniaturized replica go-karts. It’s quite amusing considering that of all the cars that did sell for at least seven figures, these four go-karts were stars of the show in their own right.
