I'm at work, so I cannot check the game to verify the correct names of menus and buttons, but anyways... In the huge mega menu (The calculator/pc-thing), under "auto commands" you have a button called "Stop selling". There you can choose the car you want to stop selling, and it will right away stop selling it in every branch you own. It also lists the build year, so that you don't stop selling the incorrect model year of a car.
