So I’d booked a car online, with Avis, using my debit card. It was for our road trip from Aspen, to Denver. I’d read their terms and conditions and read that most rentals now accept debit cards instead of credit. Turned up at Aspen airport and the agent at Avis told me otherwise. He said he couldn’t do anything as it’s NEEDS to be a credit card. My mum and I, went to all other rentals there and all of them said the same things, except Hertz where the lady didn’t have a car that needed to go to Denver. Marek (pronounced Mark) from Sixt, called us back while we were trying to figure out this big change in plan. He made an exception. He understood our disappointment and decided to help. He asked for our boarding pass to Aspen, saw our tickets out of Denver, offered us 2 options, a sedan and a BMW X3, gave us a discount, helped us figure out the toll road situation toward Denver, and messaged me later in the day to answer a question I’d asked earlier about shuttle availability at Denver Int’l airport as we were to drop the car off before opening hours. I really appreciate Marek, for his willingness to help and assist us, his friendly nature and for taking the initiative to make an exception to the rules, to think out of the box. Most people, wouldn’t bother. Thanks Marek. Our trip was possible, because of your help.

I had to rent a car while mine was being repaired. Crystal was fantastic! She walked me through the process and then gave me an upgrade for being a first time user. I will now recommend Sixt to family and friends because of her great care. Thank you!

Crystal, at Aspen airport, was a breath of fresh air to work with! She was friendly, accessed my reservation quickly, and upgraded me at no additional cost. Easy 5 star experience!
The SIXT agent was extremely professional and provided some great tips for places to visit during our visit.
Great Service checking in!
Service was amazing, Crystal was great to work with. Helped me out so much with extending my rental while on vacation. 10/10 would rent from her again.

Crystal, the service agent at Sixt, at Aspen Airport, was super helpful and enabled a seamless experience when I had to extend my agreement due to flight cancellations. Her help gave me peace of mind and one less thing to juggle!
