We arrived at HERTZ earlier than the scheduled time, and the reserved car model was not available. The staff said they could only offer an electric car or a manual transmission car unless I paid double the order price for an upgrade. I declined and decided to wait. After waiting for nearly 2 hours, another experienced staff member managed to provide me with an SUV one size smaller than what I had reserved. I had booked a small SUV, which was supposed to fit three 24-inch suitcases in the trunk, but they gave me a compact SUV that barely fit two 24-inch suitcases. After placing the luggage, there was barely room for even a large bottle of water in the trunk. Having rented cars internationally five or six times, this was the only time a rental company downgraded my car model. The service at HERTZ Heathrow Airport branch was really disappointing. The car itself was in good condition, quite new, with only a few thousand miles on it.

The staff at the airport rental store were very polite, and because it was early in the morning, there was no queue.

The service was good, but the location is a bit far. Even with the airport shuttle, it's still a distance.

With Hertz, I have always found the best car for my budget. They are very quick to process your booking and handover the keys.

They could not check the car in quickly as it was a 30 day hire. I was there for almost an hour and a half whilst their computer gave problems. They then tried to bill me one day extra at a high day rate when I actually handed it in a day early! They then corrected this but I must look at my statement next month to ensure they did not bill me extra.
