The Mustang and Shelby Club of Long Island held its annual "Mustang Showdown" at Levittown Ford on Hempstead Turnpike on July 28 for Mustang, Shelby and other classic-car enthusiasts to show off their prized autos. Levittown Ford also donated a portion of the proceeds from the show to the Wounded Warrior Project to help disabled U.S. veterans. Here is a gallery of some of the vehicles on display.
