The cost of car sharing usually depends on the type of vehicle you’re borrowing and the length of time you need it. Avail also charges a general insurance fee to manage our policy, which can be waived if you provide proof of having your own car insurance. There are also additional fees that may be incurred, such as if you smoke in the vehicle, drive with pets or exceed our mileage limit of 200 miles per day, which is charged at $0.50 for every additional mile.
