Overall pleasant, but would like an explanation regarding the quoted amount vs the billed amount

Very good, smooth experience.

The staff at the rental location were quite professional, patiently answering all my questions about vehicle operation. The car was relatively new and easy to handle, which was very helpful for me as a first-time driver of a right-hand drive car. He didn't try to sell me anything, but I decided to add full insurance at the store for peace of mind. It wasn't expensive, just over 100 pounds for 7 days. Because the rural roads in the UK are narrow, I initially wasn't used to it and scratched the wheels. When I returned the car, the staff said they would hold my 500-pound deposit and refund it after the insurance claim. The refund was processed in a few days. Traveling through the Cotswolds without a car would be inconvenient; the most enjoyable part of my trip to the UK was driving through the countryside.

There were additional fees, more than what was shown on the order. The staff said everyone has to pay some sort of location fee. The car was almost brand new, only a thousand kilometers.

They did not push insurance sales. The car pickup was quite fast, with two cars to choose from. We had more luggage and took some time to decide which car to take. I rented a RAV4 but ended up with an Eclipse, which had significantly less space. Overall, though, I was satisfied.

Very good, efficient rental and return process. There is a shuttle bus to and from the airport, which is quite convenient. Booked a Passat automatic, but got an Insignia instead. The car was very new with plenty of interior space, and the trunk could fit three 24-inch suitcases. The built-in English GPS was useful (if you're not confident with English, it's recommended to rent a free GPS from the QEEQ website).
