To add to the list of troubles with Sixt- I discovered that collision damage waivers are really at the discretion of Sixt, and their policy is to deny everything.

I recently rented a car and while driving on the highway I put my coffee down and accidentally swerved into the side bumper rail. It was a complete accident (my first one) and at the time I thought, thank god I got the collision damage insurance (which cost me half of the total car rental price). The car was only physically damaged. I returned the car and reported the incident and was shocked when instead of a bill for the maximum amount as part of the insurance, I had the full bill- over 13,000 (which when I look up the value of the car, is the value of the entire car).

When I asked why the full amount, it is allegedly because of "gross negligence" on my part and therefore the insurance I paid for is invalid. I have been asking for an explanation of how drinking a beverage is "gross negligence", and have received none, only directives to pay. I am left wondering why even offer collision damage insurance if it is not really an offer. Also I want to add that finding the information for the insurance and its exclusion criteria was one of the most difficult things I have done recently, and so at the very least transparency would be appreciated.

I am a Premium customer at Sixt, recently switched over from Avis, and it's safe to say I will never return to Sixt again.
