We arrived at HERTZ earlier than the scheduled pickup time, and they didn't have the reserved model available. The staff said we could only choose either a fully electric car or a manual transmission vehicle, or pay double the order price to upgrade to another option. I refused and suggested waiting to see what could be done. After waiting for nearly two hours, a senior employee helped us by offering a smaller SUV model compared to what we had booked. I had reserved a compact SUV capable of fitting three 24-inch suitcases in the trunk, but we were given a subcompact SUV where only two 24-inch suitcases barely fit. After storing the luggage, there was hardly any space left—even a large bottle of mineral water couldn't fit. I've rented cars abroad five or six times before, and this was the only instance where the rental company downgraded the car model. The service at the HERTZ Heathrow Airport branch is genuinely poor. However, the vehicle itself was in good condition—very new with only a few thousand miles driven.

They did not notify me of the violation in time. After one day, they directly deducted the service fee and the fine without permission. This is very upsetting.

Okay

Overall satisfied, especially with the patient explanation of various terms when picking up the car, and the good condition of the vehicle. I filled the tank before returning the car, but upon reaching the airport location, I noticed the fuel level was slightly below full. So, I went out again to top it up. Upon my second return, the staff did not inform me or give any hints and just printed a bill (I assume). I took it and went to the airport. At the airport, I discovered an additional charge of £7.62, presumably for the fuel shortage, apart from the usual rental fee and taxes. Calling them later, I found out their service time was over (after 18:00). I don't understand this practice, and maybe the staff was careless, but I am not satisfied with this outcome.

Hertz is located a bit far, but there's a shuttle bus which helps. I came from Terminal 5, the queue was short in the morning, and I got the car quickly. The service was alright, but they recommended too many things. You need to say No to everything, especially when they emphasize that fuel prices are cheaper than the market. If you ask whether you can get a refund for any leftover fuel, they say no. I almost got fooled. It's hard to return the car with an empty tank precisely. Also, after getting the car, carefully check its condition. I found a few scratches that weren't noted in the inspection report, so you need to inform them yourself.
