The car provided was already large enough, but they recommended a more expensive one, which I wasn't very happy about. Adding an additional driver costs £14 per day. We picked up the car in London and drove to Oxford and Cambridge. The countryside roads in the UK are narrow and traffic is fast, so careful driving is necessary.

There was basically no service when picking up the car. They just gave me the keys and a parking location, so I had to find the car myself. Only after asking did they provide me with a paper receipt. I found noticeable scratches on both sides of the car. I had to figure out how to use the car controls on my own. When returning the car, there was no one to inspect it; you just leave the keys as instructed and can leave.

Unhappy with AVIS service. They downgraded my reserved C-Class Mercedes to an A-Class just because I didn't have two credit cards for the deposit (one card suffices in other European countries). They didn't even refund the price difference. Ridiculous!

The car was very new and easy to drive.

Not bad, the car is very new.
