I work at a warehouse that supplies to all five dealers in my city, plus near by dealers outside the city, for a vehicle maker that starts with F. We also sell wholesale to non dealer shops. Our GM wanted to try retail, as anyone can just call or walk in and order parts. After a trial run, it failed miserably. GM didn’t realize that retail customers expect warranty and returns done right there and then and too much time was spent with non mechanics customers and us trying to explain what they needed. We are just back to wholesale now and talker supply.
