1. The rental process is very simple. There's no credit card deposit, authorization, or vehicle inspection involved. Picking up and returning the car is hassle-free! 2. The car is a diesel version with plenty of power, perfect for the uneven terrain of Cappadocia! 3. One reminder: They won't hold a sign to meet you. When you are waiting for your luggage, you need to call them, inform them when you will be at the terminal entrance, and confirm how long they will take to arrive. Otherwise, you might end up waiting in the cold for nearly 30 minutes like we did. 4. If you are not going to Lake Tuz, adding 100 lira worth of fuel is enough. There are many gas stations along the way. We added 150 lira and still had 2 bars of fuel left when we returned the car. Since we picked up the car with an empty tank, it was unavoidable to waste some fuel.
