Originally I had booked a BMW IX1 for two days. However, I was very worried about the car I had rented in Barcelona (theft, broken windows, etc.). To ease my worries, Michael suggested Sixt's Full protection insurance. I already had CDW insurance from rentalcar.com, but I was still worried about the car, so I added Sixt's insurance to Michael's kind offer. Then Michael spoke to the branch manager and suggested that I could use a BMW i7 for the same price I had already paid. When I rented the car, Michael assured me that I had Full protection insurance. I returned the BMW i7 without any damage, and Sixt gave me another piece of good news. Sixt added a 20 euro discount to my insurance premium because I had to drive a larger BMW i7 instead of the BMW IX1 that I had originally booked. I am very happy with my friendly rental experience with Sixt-Rambla de Catalunya in Barcelona.
