Absolute scam - avoid this company!
Avoid this company! They will scam you. I dropped off a car and the check-in person had to walk around the car twice before finding a tiny scratch almost on the underside of the car (if you squint, you might be able to see it in my picture). He charged me 420 euros for it! I took a video of the car when I picked it up, but I didn't get on my hands and knees to record the underside of the car, so I can't prove it wasn't there before. Another couple on the courtesy shuttle had just dealt with something similar.
We've rented from several other companies in Spain like MalagaCar without issue. If you do go with this company, get their insurance and photograph EVERY part of the car, including underneath. I will never rent from ClickRent again - such a scam!
