Good

They arranged a car of the same class very quickly.

Easy to find, it's right in the city center. When you see the huge Hertz sign, you're almost there...

The basic insurance was initially said to be over 1000 AUD, but it turned out to be over 2800 AUD. They told us that for any accident, they would deduct more than 2800 AUD, so we reluctantly paid an extra 34 AUD per day for insurance. As a result, the rental fee almost doubled. The service quality of international car rental companies is generally average; it's often difficult to reach them by phone.

Car up graded as middle seat belt in back seat did not work.

Like: Sign board on the return vehicle is not clear when we entering the Sydney International Airport Terminal 1. I have missed the entry and drove up to departure hall.
