Notice One Star - I would rate SIXT as a ZERO if possible.
I reserved an Audi A7 online about two or three months before our trip. We wanted a comfortable powerful sedan for our trip around Switzerland. When we arrived at the SIXT agency in Basel, we were given an old POS Mercedes diesel station wagon, a C200 I think. I told the agents that we had reserved an Audi. They said that they were only required to rent us an Audi or something "similar", and that the MBZ diesel wagon was "similar". We had just gotten off a Vikings river cruise (Excellent BTW) and had no transportation. We were stuck with the MBZ. That was bad enough, but we were ripped off at the return of the car. We were charged 100 euros for dropping it off at the Sixt agency on the "wrong" side of the airport. No one ever told us that there were two sides, or that we were at the "wrong" side. We were charged for filling the tank. Forty gallons - yes, more than the tank in that little MBZ would hold. These charges were added to our credit card after we returned to the USA. I tried several times to talk to someone who could review the situation. No one would/could intervene or assist. No recourse.
Sixt must be the worst car rental company we have ever hired. Horrible. read more
