If you’re ready to move on to your next ride, the biggest question on your mind is likely: "How long will it take to sell my car online?" Whether you’re trying to clear space in the driveway or need the funds for a deposit, time is of the essence.
In the Australian market, the answer varies wildly depending on which route you take.
