This time they have spent more time with the car. They have checked the window seals, door seals, cowl, and evap system. Hopefully I get my car back this morning. The service manager has been helpful, with everything. He had no hesitation in replacing the carpets or letting me pick what rental car I wanted to use. He said he has a shelby, so he can relate to me being a mustang fan. Stuff happens, but hopefully it will be fixed this time.
