There was a double charge issue. I had already paid in full on the rental website, but was charged an additional £250 rental fee and £252 deposit for damages when picking up the car. I told them I had already paid to the rental company, and they said it was a deposit. My understanding was that the deposit would be refunded upon returning the car. I contacted the rental company, and customer service assured me it was a pre-authorization and I should just pick up the car. Upon return, the damage deposit was refunded, but the £250 rental fee was not. The car company said the rental company would refund me. I called the rental company to report the issue, and the customer service mentioned they would handle it after the New Year holiday. Needing to catch a flight, I returned the car and left. Now 10 days have passed, and the car company is still verifying the issue. It seems the process in the UK is quite slow.

They kept pushing us to rent more expensive cars.

Eurocar is relatively cost-effective among car rental companies. The car condition is good, and being a chain company, it provides a reliable service. They don’t have hidden fees or unreasonable deposit charges like smaller companies. Reminder to read the terms carefully. In Europe, Eurocar is recommended over Avis as it's cheaper while maintaining quality. For the wealthy, any choice is fine.

Upgrade to an automatic was very welcome for London driving.

Like: Service staff AMINAH at London Heathrow pick up was excellent. Friendly and efficient...even though it was near Christmas and I arrived at a time when the colleagues were going to take a group photo, she helped out immediately and was very friendly and helpful. Good job Aminah and thank you!
Dislike: Returning the car was a pain. There was no transport back to civilisation. I had to struggle to get out. If there was a courtesy bus back to the Terminals, nobody told me!!!! I walked and walked to find a bus stop to my hotel.
