One big problem is that you likely need the car until you leave. If so, you will be limited to selling to used car dealers, like CarMax. A private buyer wil want the car immediately and will probably not be willing to take the risk of you driving for a few months after they agree to buy the car. On the plus side, we had a van that CarMax offered us a great price on; we took it. If it is low mileage, nearly new, and in great shape, get quotes from new car dealers. If it’s a Toyota, a Toyota dealer will offer abetter price for it than if you try to sell a Ford to a Toyota dealer.
