Customer Reviews
So happy with my SUV rental!
Oh my gosh, I just rented an SUV from Sixt for my family's road trip and it was absolutely perfect! The booking process was super easy on their app. We got a great deal and the car was exactly what we needed. It was spacious and comfortable for all of us. I'm definitely going to use them again for our next trip and tell all my friends about it!
Easy premium wagon rental
Needed a premium wagon for a family event, and Sixt had exactly what I was looking for. Booking online was straightforward. Pickup at the airport was a breeze, took maybe 15 minutes. The car was nice and clean. No complaints, it was a good rental experience.
Good car, minor service hiccup
I rented an Audi for a week-long vacation. The car itself was fantastic, very clean and drove perfectly. Pickup was fairly efficient, though there was a slight delay at the counter because they were short-staffed. The return was quick, no issues there. Overall, I'm satisfied with the value I got, but a quicker counter experience would make it even better.
Decent value for a first timer
As a first-time renter with Sixt, I was looking for the best deal. I managed to get a good rate on a compact car for a weekend trip, mainly because I booked early. The price seemed fair compared to competitors. The car was basic but got the job done. I think it was worth what I paid.
Consistently good rental experience
I rented a Mercedes-Benz from Sixt again for a business trip, and as usual, everything was smooth. This is my third time using them this year, and the pickup process was quick just like my previous rentals. The car was clean and well-maintained. It's why I keep coming back.

Wondering about the whole under 25 thing. My buddy is 23 and wants to split a rental for a road trip. Is Sixt going to hit us with a crazy surcharge or is it somewhat reasonable?
Hey, thinking about booking a luxury car for a weekend trip to Miami. Does Sixt actually have those super nice BMWs or is it just 'or similar' and you end up with something way less cool?
