Great cars and status match; clearer add-on guidance would improve checkout
I’ve had a very positive overall experience with SIXT. They matched my Hertz status, booking feels easy and tech-forward, and the fleet is more interesting and fun than many competitors. My one concern was the online check-in process. The optional protection and add-on screens felt more focused on alarming customers about worst-case costs if they declined coverage or extras than on helping them understand what they may already have through personal auto insurance or an Amex card. The same clarity would be welcome for toll transponders and other add-ons. The upsell process was also extensive. By the time I had reviewed the options after selecting a vehicle, too much time had passed and I lost that car because it was no longer available. That was frustrating and interrupted an otherwise excellent booking experience. I encourage SIXT to present choices more transparently: explain what each option covers, what it does not cover, and provide straightforward guidance for customers who already have outside coverage. A simple in-app help tool or chatbot could make these decisions much easier. I will definitely rent with SIXT again—the booking, pickup, return, status match, and vehicle selection have all been excellent. But this stage of the customer journey feels unnecessarily stressful and would benefit from a more consumer-centered approach.
