Be careful of the only car rental in town, Enterprise on Carlisle Street. They have dubious practices. For example, they give you a car with empty gas, and upon return they charge you full gas. Also, their cars are pre-scratched under the front headlights, so if you decline insurance, they are ready to charge you for alleged "damage" to their cars.
