I had no idea what to expect from Sixt because I have never heard of them. However, they were half the price of others during the pandemic and the overpricing others have done. Upon arrival, they offered me a free upgrade which was appreciated. Was very easy and smooth.
During my rental my vehicle was broken into the passenger window was smashed in. I thought the already traumatic experience of my wife's stuff being stolen would be made worse when I told them. Instead, I was told to bring in the vehicle and they would provide a new vehicle at no cost. Not only that, they gave me ANOTHER upgrade as the guys felt bad for what we went though, though it was no fault of theirs. I WILL use sixt again going forward and wouldn't hesitate to recommend them to anyone. Kudos to Sixt for providing LDW to all rentals without charging extra fees!
