Cheap Car Rentals in Colorado from $52

The car I booked on Kayak was not available, so I ended up being up-charged about $175 for a different vehicle. Upon returning the vehicle, the Sixt employee (in Denver) pointed to a TINY chip on the windshield and said he was concerned about it and essentially tried to charge me extra! I was NOT hit by a rock and the vehicle was parked inside the entire time. I asked for a receipt at the time of returning the vehicle and he said he could not provide me with one and it would be emailed to me. The whole experience was shady and I will not be using Sixt ever again.

All good except for unnecessary running boards which made getting in and out of vehicle difficult.

Madison at the counter was super helpful and provided excellent service.

Still pretty pricey for rental cars but definitely the best deal I found out there. I tried to shift the dates about a month out from my original reservation date and the price was going to double. A bit ridiculous. I also had issues with the Keysense in the car that controls all of the electronic alerts. Was distracting having alerts going off almost leading to crashing due to being startled, & frustrating with the volume limit in the car, not being able to hear phone calls or directions. Had to plug phone into external speaker. Tried to call and talked to several costumer service representatives about trying to find the keysense PIN number for the car, and no one was able to help. That was my biggest frustration with the car.

It was 9 pm and most of the people that were in line did not have a reservation. When it was my turn in line, after waiting an hour in line, I was given a car that I did not purchase. Then I received a vehicle that was dirty and had trash in it. Then I received a damaged vehicle. I was offered a refund for an extra day, but was still charged over full price for the rental. First and last time I rent with Avis. How can one place be so unorganized.

Inaccurate billing, charged me $200 more than advertised in rental agreement.

One hour wait from midnight to 1:00 to pick up the car, they ran out of my original model, and the one they gave me had some kind of wet gunk all over the inside when I got it.

The line took over an hour to get through. But nice people and free water

Over charged. Had to dispute.

There was a mix up about where to pick up the rental, but once I got to the correct location, the staff was very friendly & helpful. The car was dirty and scratched up, but it got us to where we needed to be and it was the perfect size for 4 travelers.

I called 2 weeks in advance to ask for hand controls to be put into the car since I am disabled. The lady who "helped" me sounded like she was at home eating dinner and was bothered to have to take a work call, and hung up abruptly once she had put in my request. I was a little put off, but I got a confirmation email about my request. Upon arriving in a city across the country from where I live, as a severely disabled person, the Hertz station had no car with hand controls, and said that Hertz corporate had not communicated to them, and that "this happens all the time". Incredibly unprofessional and putting me in a terrible situation. Worst of all, nobody from Hertz contacted me to give me the heads up that there were no cars with hand controls, so I had no time to make alternate arrangements. I should sue these dirt bags. Will never give this company any business ever again, and if you are disabled I strongly discourage you from using this rental company.

Very poor service. The staff was extremely rude and condescending. I will never rent from them again.

Please send me my invoice, ai did not get it

There was no easy way to cancel reservation. Tried calling and could never reach any one.

At arrival, rental office only had one worker and wait was over 45 minutes to get to desk. One worker way too few for this airport and time of day (4:00 PM). Drop off was easy and convenient.
