1. Firstly, when we arrived at the AVIS branch at Istanbul International Airport, we showed our booking contract. The staff printed a pick-up contract that was 693.95 euros higher than our original contract. After a brief negotiation, the staff reprinted the contract at the original booking price but swapped the car for a Ford C-MAX, which is clearly not in the same category as a Nissan Qashqai SUV. Despite the staff's assurances that the Ford C-MAX had more space, it is actually a compact car with much less space than a Qashqai. To avoid wasting time, we had no choice but to accept it. 2. The booking contract stated a price of 5929 RMB or equivalent USD, which equals 693.95 euros. Upon picking up the car, we were charged a deposit of 1173.43 USD. After returning the car, 139.31 USD was refunded, and the final charge was 1034.12 USD. With the current exchange rate, that's 6442.56 RMB or 753.08 euros, which is 59.13 euros higher than the contracted price. Please assist in inquiring what these additional charges are for. Thank you! 3. Aside from the above issues, the pick-up and return process was rather convenient. The car was very new, with an odometer reading of 7180 kilometers, in excellent condition.
