This online car auction business does not solely connect private sellers to individual buyers; it is no different than a brick and mortar dealership. But since Motobidia has not invested in a lot of overhead—large amounts of real estate and several salesmen—it can pass the savings onto the buyers. Specializing in used luxury vehicles like Audis and BMWs, this company does all of its business online, but maintains an office in Somerville. It offers completely free shipping on every vehicle it sells.
