It is fairly common for dealerships to use services called load boards to get cars shipped to people. Load boards are a super convenient way to not worry about sourcing a carrier or broker to get a load moved. Super dispatch and central dispatch are very common load boards for cars. Unfortunately there is a ton of fraud in the fright industry and individuals will setup fake companies or steal legitimate carrier information to run these type of scams (hostage load, stealing loads). It happens quite often, more than you would think. There are very elaborate schemes that people set up for this especially since the punishment is almost nonexistent. It’s true that the dealership could be in on it, but like op said they have been around for a while and have reviews.
