If you finance a car through a used car dealership, it is generally required by the lender to carry full coverage insurance on the financed vehicle. Full coverage insurance includes liability coverage, any legally required coverages, collision, and comprehensive. This is to ensure that the vehicle will be repaired or replaced if it is damaged or destroyed. The average monthly premium for full coverage car insurance in the US is $80, but it can vary depending on various factors such as the driver's record, location, and the type of car being financed. It's important to note that minimum coverage may not be sufficient to meet the requirements of a lender for a financed vehicle. It's always best to check with the specific lender to understand their insurance requirements before finalizing the car purchase.
