When picking up the car in the parking lot, I found it was not the model I had booked (a lower-tier model). I had to return to the pickup store to modify the order and finally got the reserved model.

Satisfied

The process was very smooth.

Received a free upgrade to a Grand Cherokee. The car is spacious, with a large fuel tank. Used up half a tank of gas over three days. Returning the car at Salt Lake City Airport was very convenient, as there was a gas station nearby.

I originally reserved a five-seater SUV, but they upgraded me to a seven-seater. The Ford FLEX is too long for convenient parking, so I requested a change. They gave me a Ford Explorer with just over 20,000 kilometers on it, equipped with 4WD and hill descent control. Many thanks to the American lady at the AVIS parking lot at Salt Lake City Airport, who patiently used the translation app to communicate with me and helped me get the car change. This made my driving experience in Yellowstone Park extremely comfortable.
