Easy!

The service personnel kept trying to sell me extras and their English was terrible. I had to confirm multiple times, and they were very impatient.

Even though I paid in full on QEEQ, I still had to input a lot of information at the self-service machine when picking up the car. Not sure why.

The company is quite large, with branches in various regions. There are many vehicle options available. I initially wanted to rent a Grand Cherokee, but at the counter they said it was unavailable. They offered either a Santa Fe or a more expensive Ford Edge, which I did not agree to. However, when I went to the parking lot to pick up the car, I was pleasantly surprised with a 2017 high-end GMC. It had only run over 13,000 miles, essentially a new car. Midway, the car showed a need for an oil change. I contacted customer service, and they provided three options: continue driving if the car was in good condition, switch to another car, or find a repair shop for an oil change and then get reimbursed. Later, I went to the Salt Lake City branch to exchange for another car, but they only had a mini van. So, I opted to get an oil change at a repair shop, which cost over $50 with tax. The refund was processed smoothly when I returned the car. Overall, it was a pretty smooth experience.

The service was pretty good. They tried to charge me an extra $350 for a one-way rental fee, but after showing my QEEQ order and explaining the situation, the fee was waived.

Unclear insurance details!
