Available vehicles for rent range from the Chevrolet Aveo on the low-end ($19.40 per day) to a Dodge Charger RT and BMW 3 series on the high-end (both priced at $62.92 per day). You'll get unlimited mileage as part of the rental, but you will have assorted taxes and fees added on to your total bill amounting to an additional $8 or so.
