There are many supplemental coverages you can add to your policy.
Rental reimbursement is a common add-on. It covers vehicle rentals
in the case of damages to your car or if it is stolen. Towing and
labor charges help protect you in the situation of a roadside
breakdown.
Gap coverage is recommended to those who owe more on a vehicle
than it is worth. Gap will pay the difference between the ACV for a
totaled car and the amount left on the car loan. This keeps you from
paying for a car that isn't with you anymore.
