You found a buyer for your car and you have worked out all the details: purchase price, exchange of title, cancellation of your insurance, but have you thought about the warranties you may have on your car? If the car you are selling has an extended warranty, service agreement, guaranteed auto protection or tire coverage and these warranties have not been transferred to the buyer, you could be entitled to a refund for the remainder of the warranty.
Call your provider, with your VIN handy, and request a refund. Refunds are processed in about 30 days.
