Don't go to dealerships that play these games. Seek out dealers that focus on business sales where the direct to consumer is not the bulk of their business. A lot of countryside dealers (deep country) have the same attitude. They let you drive the vehicle, if you want it they will find financing if you need them to. Sign the papers and leave. They will probably pitch some accessories and a warrantee extension. Zero drama. At those dealerships if they try that shit (sneaking in charges or playing any games) they could lose generations of business from a person. City dealerships are a pressure cooker because they have so much competition. If someone leaves they are never coming back. There is no philosophy of repeat business from a particular customer. If that happens it's just gravy.
