The Chinese staff suggested that I upgrade to a diesel vehicle, claiming the Highlander consumes six tanks of gas while the diesel would only use one. The upgrade cost $450. I was almost scammed.

Very good, the process was clear and there was no upselling of additional insurance.

Very good

Very professional. Since it's full coverage, no extra check-in or check-out inspections are needed, similar to the no-liability insurance in China. The car was very new, just over 5000 kilometers, much better than the typical 20000 kilometers in China. However, others picking up a car at Franklin Hertz should be aware that the cars are parked in a garage, and you need to drive them down yourself. It's tricky if you're not used to right-hand drive cars yet. You can ask the staff to bring the car to the ground level before handing it over. At Melbourne Airport, there's a dedicated return lane for rental cars. It's a shared lane for all rental companies and not the entrance to a private car parking. Please pay attention to this.

I had paid in full on Zuzuche, but when picking up the car, they still asked for a 200 AUD deposit, which they said would be returned the same night if there were no issues. I returned the car on February 4th and was told the refund would be processed that night, but I haven't received it yet! Contacting customer service has only gotten me a voicemail.
