When picking up the car, I asked if I had purchased full insurance. The rental company didn't inform me that the insurance contract was not with them. After returning the car, they directly deducted 380 lira. When I inquired, Grenta rental company told me the insurance was with Zuzuche and not with them, hence the direct deduction.

Check the feedback yourself. I must say, Turkey can be quite tricky.

The only downside was that they kept asking us if we wanted to buy insurance even though we already had it.

I rented a Mercedes E but received a Mercedes C. The next day, the car broke down on the highway, wasting a whole day waiting for a replacement. They replaced it with a Nissan and didn't refund the price difference. A Mercedes costs 700 per day, while a Nissan is only around 300 per day. This is truly awful.

No need to queue, the paperwork was handled very quickly.
