Enterprise, and other rental companies, offer an option to consumers where they can prepay for the amount of gasoline in the vehicle at the time of rental. You are then instructed to return the car empty. The prepay price per gallon is usually less than what is being charged at local gas stations, and generally $2 less than what Enterprise would charge you to replace the gasoline that was used. The approximate $5 (or more) per gallon charge would occur if the customer did not prepay and returned the car with the gas level less than what it was when the car was initially rented. I truly like this program and its potential for saving time and money, however there are aspects that should be changed. While this is "packaged" as an advantage to the consumer it is Enterprise that actually benefits financially, whether you prepay for not. I do not know many people who are comfortable with driving around in a car whose gas tank is near empty. I certainly do not like driving a car with a near empty gas tank, especially in the winter given the unpredictability of the weather. Thus as a frequent renter I generally prepay, always return cars with gas, and have probably given Enterprise (and others) the equivalent of $100's of dollars in gasoline. Where Enterprise makes out in this arrangement is the next customer prepays for the gasoline you/I left in that car, (sic). Consequently, Enterprise benefits from you as the renter returning the car, and from the renter taking a car. I believe that it is only fair that I and other consumers are reimbursed or compensated for the gasoline we did not use and prepaid for. Enterprise certainly has the capacity to approximate the amount of gas that is in the car when it is being rented, and can also compute the amount of gasoline that is in the car when returned. I believe this program has advantages for Enterprise, if simply saving time/resources, but takes advantage of the consumer. Would it be better for Enterprise and other rental agencies to truly demonstrate customer value by giving you back what you already paid for.
