We had rented with Sixt in Europe and always been happy, however the reviews in the states had me very nervous. That said, we had an awesome experience!
The management and employees at this location were amazing! We were taking the car one way and across state boarders. We were given a great car and there was no drop off fee!!! I was afraid to believe their quote because it was literally $1,000 cheaper than other agencies. I was uncomfortable because you don't pay up front, or at drop off...but they sent us an invoice within 48 hours and charged us their "estimated" cost!
Really fast pick up and drop off also, no walk through, just hand them the keys! I videoed the car upon pickup just to be sure...Had to step out a bit in faith, but they came through with flying colors!
