Horrible system on how they get your car. Also car was dirty inside and bugs still on windows

I waited over an hour for a customer service agent. This has never happened in my life at a car rental agency. Once I got to customer service it was very fast, the agent was very courteous, professional, and efficient. He was one of 4-5 other agents, but the other agents seemed to take much longer. This appeared to be part of the extreme wait time. I also did not get the car I wanted. I reserved a 4-door sedan, but got an SUV. I was so tired and hot (it was 90 degrees in Denver) from waiting that I didn't even ask for a different car, I just wanted to get out and leave. Drop off was much faster, but I noticed that the line for others to get their cars in the morning, was just as long as it was for me in the afternoon when picking up the car. The shuttle to the airport was ready and waiting.

Terrible drop off time. Almost missed the flight.

The car wasn't cleaned prior to our rental and it was a filth ball. We didn't find out until well on our way to the ski slopes that the rig wasn't 4x4 wheel drive. My bad for not specifying, but who makes a 2-wheel drive full-sized SUV? It defeats the purpose of an SUV. We had to purchase chains for the vehicle to comply with the Colorado Traction Law. Miscellaneous charges of more than $100 showed up on our receipt that were later removed after we called to inquire. The answer was something about computer errors. Highly suspect. Not happy !!

Car was filthy. Inside was ok. Outside looked like someone went mud running in it and hadn't washed it for months. Counter rep was very nice. Had to wait a while in line. Must have been a peak time.

Did not get the vehicle that I wanted. Took a long time waiting and finishing process at the counter.
