When picking up the car, the staff tried to sell me insurance, which I declined. Then they tried to sell me prepaid full tank gas at a bit over $2.20 per gallon, claiming it was cheaper than the city. I got confused and bought it. In hindsight, it wasn't a great deal. Firstly, the tank capacity is average for that car type, which might be more or less than my actual car's capacity. Secondly, you need to use up the fuel before returning the car, which is hard to gauge, requiring frequent refueling and mileage calculations. It's more convenient to refill near the return spot. The return process was quite fast, though. An inspector checked the car's exterior, issued a return receipt, and it was done in two or three minutes. Overall, it was a good experience.
