There is a somewhat unreasonable clause. You can pick up the car before the scheduled time, but you must note that the return time will be accordingly earlier (no notification, direct fee deduction). If you pick up the car after the scheduled time, the return time will not be extended, and it remains as per the original booking.

I lived in the US for three years, and although I didn't have any car rental experiences, I used to think Hertz, being a big company, would have standardized services. After this experience, a big NO!! I will never rent from them again! First, we booked a Jeep 2.0 on zuzuche.com, but when we got to the Los Angeles International Airport pickup point, we waited in line for 45 minutes only to be told that the car was no longer available! The worst part was that they offered us an upgrade (for extra money) to a Dodge (which is much worse than a Jeep in terms of driving experience!!!!!!!). Third, the front desk staff repeatedly tried to sell us additional insurance products (for most Chinese tourists, basic insurance is more than enough, especially if they've already bought insurance before the trip). Fourth, they lied to us, saying that filling up gas in Los Angeles by yourself would cost $9.99 per gallon (hell no, it was actually $2.69/gallon, blatant deceit, and it wasn't just one employee's behavior; it was written clearly on a blackboard at the front desk with $9.99, showing that employees commonly engage in deceptive practices), just to make us buy their fuel service waiver (which costs an extra $53). The result was that I rented a Dodge from Hertz, which had poor handling, especially on the highway. The car was very light and prone to accidents. The 4-day rental price was even higher than the 6-day rental of a Ford Mustang I booked later! Hertz, never again!

I booked economy and got a free upgrade to comfort, Friendly stuff, very good

I searched through Kayak and found in it QEEQ with a good price include insurance. However, I do not know yet if the deposit will be refunded without problems.

We were not able to collect the car. We arrived to find a queue of people waiting - there were no cars available. We waited several hours before leaving with no car. Hertz were not helpful at all. We will not be using them again.

Line was to the door when picking up. Waited ~50 minutes. Not good. Very frustrating. There has got to be a better way.
