The 100 Motorcars of Radnor Hunt is a nationally recognized motor car event. The Concours was first organized in 1997 by Michael G. Tillson, III, a Governor of the Radnor Hunt and a recognized expert on the subject of classic, sports, and racing cars.

Michael Tillson and several of the present committee members of the Concours played major roles in the organization and supervision of the Fairmount Park Vintage Grand Prix events that were held from 1990 to 1995. Featuring several hundred vintage sports racing cars, these four-day racing weekends honored the memory of the famous Fairmount Park races that took place in Philadelphia's vast Fairmount Park system during the period of the First World War. At the time, the Fairmount Park races were the premier racing events in the United States, comparable in scope and reputation to the later Vanderbilt Cup races and the Indianapolis races of the 1920s and 1930s.

It was Michael Tillson's concept to stage an elegant invitational classic car event on the spacious, historic grounds of the Radnor Hunt in Chester County that would compare to the elegance and quality of such national events as the annual Pebble Beach Concours.

The concept of the event was far removed from the typical "car show." It would be invitational, the cars would be carefully and individually selected and each car would represent an educational and aesthetic experience for guests. There would be a balance between historic, classic, sports and performance racing cars.

To recall the great traditions of the classic French Concours d'Elegance originally held in the Parc des Princes, Paris, there would be a automotive art, high-style fashion, and jewelry shows to compliment the latest fashions in motor cars.

Plans included a black-tie dinner party the night before the Concours to benefit a major charity as well as perennial beneficiaries, Thorncroft Therapeutic Riding Academy, the Willistown Conservation Trust, and the Boy Scouts of America.

Most important it would have its own unique ambience, combining the most relaxed qualities of an English garden party with a celebration of the cars that have written memorable chapters in the history of the motor car.

The Radnor Hunt Concours d'Elegance has faithfully held to those standards. Surveying carefully the progress of the Concours, the committee elected to restrict the number of entries to 100 in order to maintain very high standards and to allow the best possible display of each car. Thus evolved the concept of "The 100 Motor Cars of Radnor Hunt". For 2010, Radnor will honor Studebaker, and Triumph Motorcycles.

Radnor Hunt has been fortunate to display some of the best motor cars in the United States. In its brief history, Radnor's reputation has grown, and major collectors from as far as Florida, California and Maine have sought to win Best in Show.

In 1999 George Hahn won that honor with his 1931 Cadillac Fleetwood Sport Phaeton.

The 2000 event was captured by a 1939 Bugatti 57SC Roadster by Saoutchik and proudly presented by Jerry Sauls of Bucks County, Pennsylvania.

In 2001 Radnor honored the 100th anniversary of Rolls-Royce and fittingly, the 1926 Rolls-Royce Phantom I Salamanca of Baltimore's Charles Gillet took Best in Show. In the first year of the Timeless Elegance Award, Wendy Garthwaite DeMarco won a beautiful watch presented by Govberg Jewelers for her 1938 Bentley 4 Litre Coupe by Van Vooren.

In 2005, Joseph Cassini became the first multiple Best of Show winner with his 1930 Bentley Speed Six by Gurney Nutting. This great car was originally built for Lt. Cmdr. Glen Kidston so that he could compete in the 1930 Monte Carlo Rally. Commander Kidston was one of the famous "Bentley Boys" who achieved a kind of immortality for his spirited adventures with Bentley cars. John W.
