Business Idea - Car Swap Meet

Turn a vacant lot into a swap meet for cars only. You charge people who wish to display their car in your lot for a flat fee for a specific day or week - no selling or buying on your part - your only cost is your ad to attract sellers and buyers and whatever insurance costs to cover “trip insurance” - so that anybody that may injure him or herself by tripping on a crack is covered for their expenses. Offer a food concession for bigger profits. Who doesn’t want a hot dog or hamburger when shopping for a car?
