  Tried to scam us for damages found after we left and after they told us it looked good and everything was fine! We cannot speak directly to the location we rented the car from. They did not come out and walk around the vehicle with us, we were told to report any damages. We didnt see any damages. Apon returning , we stood at the car while the attendant walked around the vehicle. He stated everything was fine. Then 2 days later we get an email that there was damages. I called and was told they would help with the issue if I pay $30, then he said $50 and the damage was $150. I told him that apon returning the inspector of the vehicle said everything was fine and I am not paying anything. He then said there was $250.00 in damage and if we dont pay $150.00 we can never rent again. Denver Sixt is a total rip off and we will never rent another vehicle again. We have a long track record with Sixt in florida, and never had any issues like this before. I would like a supervisor from the Denver location to call me. Not some foreigner from another country.

  Very disappointed. I returned my vehicle feb1st. They still have not closed my ticket out. I rent from Sixt weekly due to work in DC. Colorado is by far the worst. I’ve NEVER experienced this but now I’ll be considering of not renting from them ever on travel again. They are so hard to get ahold of. Truck was “ready” when I arrived. A guy asked if he can clean it real quick. That should have been the first sign. I get the truck back, and the gas is low. They said they would discount from my rental. Upon return, I was told I was all good, didn’t have to sign anything (which you normally do) I continued to ask if that’s it. She said yes. I have been trying to reach someone and when I do I get rude customer service with so much noise in the background it’s hard to understand. Do better Sixt!!!!

  Good pricing + elite sales staff, but lost & found process needs work I chose Sixt at Denver International Airport because the pricing was excellent — honestly below market — and I’m glad I did. The staff was also outstanding: courteous, helpful, and clearly well-trained. As a business owner who recognizes sales talent, I have to give credit where it’s due. Their counter team runs a smart, structured upgrade experience. The process is straightforward: you book an affordable class online, then at the counter they walk you through upgrade options in a way that’s confident, professional, and (yes) persuasive. In my case, I booked a standard vehicle and was shown what was available in the booked class, then offered upgrades step-by-step. We went through a few options, talked through what made sense for my week and client meetings, and ultimately landed on a Volvo for a $160 upgrade. Did I probably pay more than I planned? Sure. But I also respect a well-executed sales process — and they played it cleanly and effectively. The only reason this is 4 stars instead of 5 is the lost item / lost & found experience. I left an item at the counter and couldn’t call the location directly. I had to go through corporate, wait on hold, and then fill out an online form. Several days later, I still haven’t received an acknowledgment that the form was received. That part of the experience feels outdated and unnecessarily difficult. Even the hold message felt robotic and “cheap,” which clashes with how polished the staff is in person. Bottom line: fantastic value and a top-tier counter team — but Sixt should modernize their lost & found and phone support experience to match the quality of their frontline staff.

  DISCRIMINATION, ABUSE, AND UNACCEPTABLE CONDUCT. This was one of the worst customer service experiences I have ever had with a car rental company. An employee named FATIMA canceled our confirmed reservation without valid justification and displayed an extremely rude, hostile, and unprofessional attitude from the moment we arrived. The company did not have the car we reserved and attempted to force us to rent a larger vehicle at an extra cost of $100 per day, adding hundreds of dollars in unexpected charges. They also tried to push unnecessary insurance, even after we clearly stated we would use our own. When we refused to accept these unfair upsells, the employee became angry and retaliatory. Her behavior felt discriminatory and demeaning, especially because our first language is Spanish. Ironically, she spoke Spanish with coworkers but refused to speak Spanish with us, which felt intentional and disrespectful. She later refused service under a false accusation that we took a photo, which never happened. This appeared to be an excuse to deny us service after we refused to pay extra. Even worse, she made intimidating and inappropriate comments related to immigration, which was deeply offensive, threatening, and completely unacceptable in any professional environment. To make matters worse, we have still not received our refund, leaving us out of both time and money. This experience reflects serious issues with ethics, customer treatment, transparency, and management oversight. Someone with this attitude and behavior should not be representing any customer-facing business. There are far better, more honest, and more professional rental companies. Avoid this location at all costs.

  This will be our first and absolutely last rental with SIXT. The experience at the Denver airport location was nothing short of a polished bait‑and‑switch operation. I prepaid in November 2025 for an “Extraordinary” BMW X5 and even called ahead to confirm that an AWD vehicle was required. I was assured this was noted in my reservation. Yet when I arrived in January 2026 to pick up the vehicle, I was informed—without apology—that no BMW X5 with AWD, or anything remotely equivalent, was available. My only options were a pickup truck or a Mazda CX‑90. Since I am not comfortable driving a large pickup, I reluctantly accepted the Mazda. That’s when the situation became even more absurd: I was told the Mazda CX‑90 was considered an upgrade from the BMW X5 and that I would be charged an additional daily fee. With my wife and two‑year‑old daughter waiting, I had no choice but to proceed, resulting in an extra $300 added to my already prepaid reservation. If this is not a textbook example of bait‑and‑switch tactics, I don’t know what is. To make matters worse, the CX‑90 was in unacceptable condition. The vehicle had 21 documented damages, including multiple deep scratches over a foot long and a dent in the trunk the size of a fist. The exterior was filthy, and the overall driving experience was sub‑par. In short: if you book a BMW or Mercedes at this location, be prepared to be pressured into a Mazda “upgrade” and charged extra for the privilege. This operation is misleading, unprofessional, and entirely unworthy of customer trust.
