The Permco Grand Prix of Mid-Ohio, the longest continuously-running spectator event at the track, returns on June 20-22 for its 43rd running. The Sportscar Vintage Racing Association-sanctioned weekend will provide fans a wide array of classic and modern race cars to enjoy, including the ground-pounding Trans Am Series. Off track, the British Car Showdown will fill the infield on Saturday, and on Sunday, classics of all makes and models will be on display for the Concours d'Elegance.
