One way car rentals average between $100 - $200 a day.. and can be much more depending on the vehicle, time of year, pick up and drop off city, etc. Car rental companies will either charge a base rate plus a drop off fee or just charge a higher rate per day.. make sure to compare rates with several companies to make sure that you're getting the best deal. Try and keep the rental as few days as possible, and check rates using a discount code if you qualify.
