Quincy David "Quin" Epperly, Mar. 3, 1913-Jan. 7, 2001, was an American racing car constructor. He was born in Floyd Va. to John Wesley and Iowa Texas Epperly. After completing a correspondence course in "Theory of Aircraft Construction", Quin moved to Southern Ca. in 1940 to work for Lockheed and Pacific Airmotive. During the war, he joined the Coast Guard reserve to spend evenings after-work on watch at the Wilmington Coast Guard Patrol Base.

In the late 40's, he went to work for Frank Kurtis building racing car bodies; this led to a life-long career in the racing business.

During the mid 50's Quin opened his own shop, where he came up with a radical approach in racing car design, by placing the Offy four cylinder engine on its side, rather than in the upright position as was the usual custom for the old Indy roadsters of that era. Coined the "laydown Offy", it allowed for better high-speed aerodynamics and oval-track weight distribution.

He also built the body for the first "Spirit of America" land speed record car with the operation running out of his shop in Gardena Ca. He kept himself busy long after most men would have retired, repairing both current and historical racing engine blocks from the world over, as well as masterfully restoring vintage race cars.

Perhaps his most notable restoration was the 1961 Kimberly Cooper-Climax Type 54, the car in which Sir Jack Brabham

 began the "rear engine revolution" at Indianapolis. The restoration earned the car the coveted Monterey Cup at the 1991 Monterey Historic races, when, driven again by Sir Jack, it performed perfectly. It has since traveled to the Festival of Speed at Goodwood in 1993, to Australia in 1995 for the CART Surfer's Paradise race, to Michigan International Raceway in 1996 for the U.S. 500 (where demonstration laps at around 140mph were made), and to the California Speedway in 1997 for the Marlboro 500.

His last major project was to complete the body restoration of his own Demler Special #99 in 1998. The Demler car had finished second in the 1958 Indianapolis 500.
