The rental process was quick and the location is very close to the airport.

Easy and fast rental and return process

There is a Hertz counter at Adelaide Airport. However, when I collected my luggage and went to pick up the car, there was no one at the counter. I had to go directly to the airport parking lot, where several rental car companies have their parking areas. It was fairly convenient.

Overall, I'm quite satisfied. It's worth recommending and convenient.

Although I had some reservations about HERTZ pushing me to upgrade the car, to be fair, their service was still pretty good. The wait time in line wasn't long, and while communicating in English wasn't as convenient as in Chinese, I couldn't expect too much while abroad. At pickup, the staff informed me that my reserved Corolla wasn't available and suggested I upgrade to an Audi Q5 by paying extra. I thought it was an additional 18 AUD per day, so I accepted. Later, I found out it was actually 45 AUD per day, totaling 180 AUD for the 4 days. While I was okay with the cost, suggesting a luxury car upgrade immediately did feel a bit pushy. The Q5 was in excellent condition and very new, but there was no manual with the car, making opening the fuel cap a bit challenging. The car was great to drive, and I had no issues, making the rental experience smooth overall. I was in a hurry to leave and didn't have time to argue, so I took the risk and accepted the luxury upgrade. The 3 AUD per day charge for roadside assistance added up to a small amount, and since I realized this after the fact, I won't dwell on it.
