Since you will now own the car free and clear, you have a few other things to do, including:
In the case of your car insurance, you can keep full coverage to protect your investment or you can switch to the minimum liability-only insurance to save money. As a general rule, you should keep full coverage insurance as long as your annual payments are less than 10% of the value of the vehicle. If it’s more than that, consider switching to liability-only insurance and keeping an emergency fund for repairs.
