The car rental service was quite good.

The price was very cheap and the car was in excellent condition, with only 6000 miles driven. The high-end model included a navigation system, which was great for long trips!

First of all this location (Denver) attended Avis/Budget/Payless in the same building. The crowd waiting to rent was unbelievable. When we got there the line filled the inside of the building, went out of it and around. They abuse the fact that you've been out in the sun, by the time you get to the counter you just want to get out, so they push everything on you. It took around 80-90 minutes from the time we got to budget to the time we got to the counter. And after that we waited for a further 30 while they "got the car ready". Finally we stormed in there asking for a car that was ready and they gave us our rental.

Budget initially directed me to a car that was not in the car park, I returned to the office where the staff found me an alternative car.

Got absolutely hammered for a few gallons of gas. An extra $180. for about a quarter tank of gas? REALLY?
