They're making it right and sent me home in a brand new loaner vehicle, but it took two weeks in their shop on the repairs and then they noticed they damaged the door and had to send it to a body shop for more repairs. I am still driving a car that isn't mine for an undisclosed amount of time until mine is finished and delivered to me. I'm not knocking the dealership, but this has been one thing after another and is still not resolved. I haven't even been allowed to drive the car yet and I'm less than two weeks from having to make my first payment on it. More
