The car pickup experience was good, but the exchange process was disappointing. The fuel tank was not fully filled when picking up the car. Before returning the car, we refueled at a gas station about 40-50 kilometers from the highway exit, but the rental company claimed the fuel level was insufficient and wanted to charge 80 euros. We had to drive out again to refuel, which only cost 8 euros. Lesson learned: refuel closer to the city area before returning the car. Additionally, during the vehicle exchange, they inspected the headlights for damages and falsely accused us of using the wrong type of fuel. We argued strongly, and they eventually dropped the claim. Tips: Take a photo of the fuel gauge when picking up the car, and keep the fuel receipt for proof.
