So our experience with SIXT has been great for the times we have used them (CA, AZ, CO). From the free upgrades to the wonderful folks we have met. CO is no exception. The folks were so friendly. Even with the bit of snafu we had with our reservation not showing in the system everyone was still focused on great customer service. And from someone who comes from a CS background I am always paying attention to the service. So for the folks who want to b$$$ and moan and write their reviews, I challenge you to write about the wonderful CS experiences you have as well.

They sent a survey to ask about our check-in experience, and I was honest, so they offered to apply a $150 credit. Seems nice, right? We have still never received this credit. I tried calling them (hung up on me), and have emailed back and forth several times. They just stopped responding. Then we almost got stranded, because the battery and the key was dead, and the car almost turned off. We had to go 30 minutes out of our way to go to a store to buy a key battery. They didn't do anything to reimburse us for that. Please do not rent from this company. They will send you an email saying that they're very sorry, and they understand, but never do anything about it. Most disingenuous customer service I have ever experienced. SIXT Response: Hello Nicholas, we're truly sorry to hear about your frustrating experience with the check-in process and the issues with the car key battery. We apologise for the inconvenience and the lack of follow-up regarding the credit and your attempts to reach us. Your feedback is invaluable, and we are committed to improving our service. Thank you for bringing these matters to our attention. -Jean Follow-Up Review: The company's response proves my point--most disingenuous customer service. No solution, no promise to fix anything...just a bunch of empty words. Do not use this company, they are horrible.

If I'd make any changes or suggestions, it would only be a bit more guidance in the drop off at a different location. I expected the booths in springs to be open late and was left a little puzzled. After some digging I figured it out just fine though! They abide by state laws, while also not being too terribly greedy. I walked over after a bad experience with the competition next door, and was surprised at how easy it was for a walk in / same day rental! I ended up saving money in the long run with them too. Awesome team over in Denver and COS! Definitely earned my loyalty for the next time I need a rental.

Our insurance policy covers rentals so we have no need to do that. I didn't have our insurance policy number with me when I got to their office however, so I had to call my agent. Don't make that mistake. I was thankful it was during office hours! My husband and I laughed later about the car rental agent who tried to talk me into a bigger vehicle. She didn't think the Nissan we rented was big enough for 2. It was actually big enough for 5. We were allowed to extend our rentals longer, with no problem. After we extended it, our relatives were visiting offered us the use of their car so Routes gave us a full refund for the days we didn't use when we returned it early. So we did appreciate the flexibility

We were also charged a daily toll rate, although there were no tolls we crossed. We were also told it would be cheaper for them to refuel the car than to fill it up ourselves. We spent $20 filling the tank before returning it, and were charged $37.80 for fuel. The vehicle we were given had a broken trunk latch that appeared to be temporarily held together with a piece of metal. The trunk would unexpectedly open while driving, which created serious safety concerns. Overall, the pricing transparency and condition of the vehicle did not match what was promised at pickup. I would strongly recommend that future customers carefully review all charges in detail and inspect the vehicle thoroughly before driving off. Rent thought Sixt! They were wonderful and less than half the price of Routes for the same amount of days.

Terry just spent 45 minutes with one person and before that it was 20 minutes. Honestly he was averaging 10 minutes a person until the very end. Music skip never got shut off. I hate this place. FYI Terry was doing his best with what he had. A slow system, no other agents and a shitty sound system.

I tried Budget this visit. Believe it or not, it's was an upgrade from the place I usually try…read more After this rental, I realize that it's not an upgrade. Longer lines, tension between the written word and the action, and a car that was possibly the worst performing car I've driven. The shuttle picked us up quickly, which was great! The driver was nice and helpful. Then, more than 30 minutes waiting, even after doing the online checkin. They needed to verify documents, so there is no benefit to the online checkin, you're in the same line as everyone. Was told I'd be charged a $200 deposit, no problem. Then, they charged a $250 deposit. That would have been ok, I just like to have words and action to match. The car was a standard SUV. The car was such a gutless gas-guzzling SUV. Returning the car was odd. I pulled up and into the line of cars. After 10 minutes, I began to go inside and a worker motioned for me to move the car over to the line next to the one I parked. I moved, he was gone. I just walked around the car and filmed its condition, took pictures of the clean interior, and the full gas level. I went to the bus. So very strange. And, the shuttle driver was great, a nice guy that was very helpful to everyone. The drivers earned the two stars.
