Where can I buy GAP insurance?

GAP is commonly offered by dealers, but many auto insurers and credit unions also sell it, sometimes for less. Dealer GAP is often rolled into the loan, meaning you pay interest on it. Compare the cost and terms, including any coverage limits and deductible coverage. If you pay off the loan early or sell the car, ask whether you're eligible for a prorated refund. GAP is optional and should never be a condition of loan approval.
