Franchise dealers (sell new cars) especially larger groups tend to be more modern and less shady. But it can also come down to a lousy salesperson or finance guy. Do your research on pricing, your credit rating (secure your own ahead to keep them honest) and the history report (all of which van be found on shopping sites like Cargurus or auto trader) and above all, don’t fall in love with the car. Be prepared to walk if something doesn’t seem right
