My dealership is trying to find a better way to source our used cars. We currently get a lot of our inventory from Enterprise and from auction, with some coming from trade-ins. But we want to get away from our dependency on the auction and Enterprise. I don't think that we are large enough to have a dedicated "buy center" (two new dealerships and one used center on property, two small satellite used shops across town). Has anyone had luck with a third party service like VAN? Has anyone set up a successful system not using any of the above methods?
