Can you believe it? It was Feb. 26, 1944 – 79 years ago – when seven sports car enthusiasts met at the Boston, MA, home of Chapin Wallour to form a club dedicated to the preservation of sports cars. That small gathering started the 51, an organization that has gone on to change the face of motorsports for enthusiasts in the United States.

The Club’s original constitution stated membership would be restricted to owners of sports cars. Back then, aspiring colleagues had to be sponsored by a current member, seconded by another, and approved by unanimous vote of officers for inclusion. Today, 51 is very, very different.

In 2023, anyone across the country can join 51 and have #funwithcars by taking part in a multitude of motorsport activities. There’s wheel-to-wheel road racing, of course, but also marshaling and event organization that puts anyone close to the action. Beyond that exists RoadRally, Solo, Track Night in America, HillClimb, Time Trials, RallyCross, and Enduro events that offer everyone the chance to get off the sidelines and into the action.
