My experience was terrible. I booked a car online and paid. When I went to collect the car I was told that I needed a credit card. I hadn't been aware of this as I've never rented a car before. I believe that this should be made clear at the time of payment in red/bold print! As a consequence I was stranded - without no transport. I had to wait hours for a bus at the airport that, in turn, took hours to get me to my destination. And so, completely ruining my arrangements and trip! Customer service were very uncaring - I should have read the terms and conditions was all they said. The credit card is referred to here, but in very small print and easily missed, especially if you are in a rush booking. I'll never use auto Europe again.
