If you are concerned about the safety of your vehicle, you can contact the dealership and inquire about their policies on storing vehicles on their property. They may have specific procedures or requirements that you need to follow in order to ensure that your vehicle is not towed or impounded.
It's important to note that if the dealership does take possession of your vehicle without your consent, you may have legal recourse and may be able to pursue compensation for any damages or losses incurred. However, it's always best to clarify any concerns or questions with the dealership directly to avoid potential misunderstandings or conflicts.
