Everything went well

Service efficiency is average. Returning the car in the afternoon needs improvement. The car key should be placed in a prominent location at the rental company, not handed over to airport security. After working hours, it was difficult to find the security personnel. I had to ask several people and wait a long time to find where the key was left.

Very disappointed in having to pay a £700 deposit

The rental company strongly pushed other premium models and insurance. I mentioned I already had insurance and would not purchase more. After I declined, they switched the Mercedes to an Audi and claimed that without upgrading there would be no navigation (although the Audi did have navigation). I had seen the Mercedes model when I arrived, but the company insisted it was unavailable. The service experience was not good. Fortunately, the Audi A5 was in good condition, so I didn't pursue the matter further.

Customer service at pickup was dreadful. Wasted over an hour. Tyre pressure warning after driving for 10 minutes, had to deal with this myself after ringing the incident line. Not a good experience and have registered a complaint.

Fine

Car very good, staff also.
