I wanted to make a reservation for my last days in Bilbao/Basque Country, and Economy Car Rentals came up with a great offer, some 9 Euros for a 3-day car rental, so I made the reservation. When I got the local car rental office, they told me that it would be some 120 Euros in total! As I had quite limited time and had already made my plans, I had to give in. It was a total robbery, an absolute disaster! I sent them an e-mail with all documents attached couple of weeks ago, no response whatsoever yet! If you receive such an attractive offer from this company, please be aware that there's something weird, and if I were you, I wouldn't rent any car from them.
