Very disappointing...
When I picked up the car at Seville Airport, I was confronted with another €40 for out of office hours payment and another €40 for return location (Malaga) being different then pick up.
Both these details (pickup time and return location) had been filled in at their site to get a qoute, but only after having made the payment in the confirmation details, somewhere between the lines they start to speak about these extra cost.
