Returning the car was very convenient. Everything went smoothly, and there was no need for additional services. At Los Angeles airport, a friendly worker scanned the barcode inside the door and gave the car a quick look before saying it was okay. He also kindly told me where to catch the airport shuttle. However, I encountered an issue when picking up the car because I didn't have a driver's license notarized. The rental point refused to give me the car, and calling QEEQ was useless as no one answered! Luckily, there was an attachment online similar to a notarized document. After filling it out as required, the rental point quickly handed over the car, and the rest of the trip went smoothly.
