Despite booking early, there were no Mercedes C-Class cars available, and there was no option to upgrade to a higher class car even with extra payment. Reluctantly, I had to accept a Passat with a small refund.

The rental process was quite smooth

A very poor car rental experience. The vehicle did not match the booking level.

Slow! It took me 50 minutes to pick up the car! They said the tank wasn't full, went to get gas, said it would take 10 minutes, came back after 20 minutes and the tank still wasn't full! The location is unclear, and the staff's English is terrible!

1. Both the Kayseri Airport pickup point and the Izmir Airport drop-off point were not clearly marked, causing quite some confusion. 2. The car provided had an empty fuel tank, and I had to put in some fuel to start it! Finding a gas station immediately after starting the journey is very inconvenient for first-time visitors. 3. The front tires of the car were severely worn out with barely any tread left, which was nerve-wracking during driving.
