I have an idea for a used dealership and here is the diea. there is a high-traffic site that used to be a gas station that's been sitting empty for years (it sits between two gas stations, so the site doesn't need a third). The area has many dealerships nearby, Ford and Chrysler and Harley, I think. If I approached the dealerships about selling their trade-ins at the gas station site, would that make sense? Would they be willing to have me sell their used inventory on a commission or consignment basis? I'm thinking that they probably just sell the cars to a big wholesaler anyway, so maybe they will get a better rate by working with me. Or maybe I'm totally off base. This is in the US. Thanks
