If all the features worked, it'd be great – SIXT rent, share, ride & plus Review

The app is pretty promising, allows me to easily browse car options and reserve, along with seeing upcoming and historical reservations. However, some of the features (such as preselecting your car) never work for me. It also only allows me to preselect my car after my reservation starts, whereas you probably want to select your car before going in to pick it up. When it gives you the option to call a hotline, it only calls an international number.
