Do not use unless you have excess insurance!! We rented from Kefalonia airport. All very nice at pickup. Nice new Citroen C3. So far so good but, boy, did it change when we returned the car! Like vultures around a dead animal 4 people descended on the car on didn't stop till they found the most minor damage to the rubber skirt under the front bumper. May have been there before we took the car, I never crawled on my hands and knees to find out. So, end result was a retention of 306 euros from the damage deposit for supply and fit a new bumper! Yes! You can get the part on eBay for £30. I was in no position to argue as I had to get to the airport to check in. When back home I instigated an email correspondence with Green Motion and they actually admitted they had no intention of carrying out the repair unless the company they had leased the car from insisted. This is a money making exercise. They probably did the same thing to the next person that rented the same car! Luckily I got the money back from my car hire excess insurance but this does not condone what they did. Plenty of other car rental companies are available (Greekstones). Pay a bit more and avoid getting ripped off. I am still angry and this was a couple of months ago!
