I rent a car from Greenmotion in Istanbul Sabiha Gökcen Airport, worst decision ever. I rent many cars in Istabul as well in other foreign cities like Malaga, Malta or Sardegna but this was the most FRAUDULENT one ever. First of all, they let you wait for an hour at the airport because they are not capable enough to consult two customers at the same time due to their loads of papers and bureaucracy. After returning the car they do literally EVERYTHING to let you pay any damage EVEN IF YOU HAVE FULL INSURANCE. Important!! Please stay away from them, they let you sign 5 or 6 on paper written documents with a load of text (I came to enjoy my holiday, wtf??) and then they try literally EVERYTHING to get any cent out of your pocket on supposed "damage" in the car. You would need a police report in order to get your insurance money back months later (I didnt have such a condition before at any of other car rental companies where I was very satisfied with). As an experienced traveller and regular customer of car rental companies trust me if I say, STAY AWAY from greenmotion. Your money is worth a more reliable and customer friendly rental company.
