The grounds of Glenview Mansion are transformed when more than 500 antique and classic automobiles go on display. From Packard to Ferrari, 32 car clubs are represented during this grand event while auto collectors and enthusiasts share fond memories of the classic cars of yesteryear. The show has a flea market, car sales area, moonbounce, and live music. Food and drink will be available for purchase. Each year, the Mayor and Council of Rockville select one vehicle to receive the Mayor and Council Award. The 2019 recipient was a Hudson Terraplane K Rumble Seat Coupe owned by Todd Harrington. Show cars must be driven onto the field, and no trailers will be allowed onto the field.
