I have been hiring many cars in all continents around the world over 30 years and I have just had the worst car hire experience ever at the hands of Alamo (Europcar) in the UK. This is not just some unjustified grumble and I am not in the habit of writing complaints to a forum, but my experience was extraordinary and a letter of complaint to the head UK office of Europcar was rebuffed with a weak attempt to justify the actions of their staff. I am writing this to suggest that you avoid Alamo/Europcar/National, or if you want to hire from them, that you take my advice at the end of this post.
I rented an Alamo car on a one-way hire to drive from one airport to another, without leaving the car and arrived without incident. On arrival, the Europcar attendant pounced on a scratch on the wheel arch and almost gleefully told me that it would cost GBP 200 to repair. I had not taken out insurance to cover damage excess and no-one from the company had inspected the vehicle prior to my departure. My wife and I reasonably argued that the damage could not have occurred while we had the car and the response of Europcar was to call the police. The police were quite sympathetic to us and we got the impression that Europcar frequently resort to police intervention when anyone dares to argue with them.
It seems to us that Alamo/Europcar may be indulging in a scam whereby they hire out cars with unrecorded damage and then charge customers who decline damage excess cover. Most car hire companies will check the car over with you when you hire from them and I usually do this myself anyway. On this day, I was in a hurry, so I took the "no damage" statement on the contract at face value - big mistake! If you wish to hire a car from these companies (and I suggest you avoid them), I strongly recommend that you inspect every inch of the car, inside and out, for damage, and note even minor scratches, bumps, blemishes, scuffs and stains on the contract. You should then phone the office to report any damage BEFORE you drive off and get the name of the person to whom you reported the damage. Another car hire victim in front of us in the queue when returning our car was accused of staining the back seat, even though he and his friend had only had the car for several hours and claimed he had not touched the back seat. He was charged damage excess.
