As mentioned on this site in the past, use of a brand name for car rental may carry little weight if a problem arises. A very long time ago we learned this when we rented from Hertz in SXM and were overcharged. When I contacted the Hertz Customer Service folks when we got home I was informed that SXM Hertz was not part of Hertz USA. They accommodated us as a "good will" action but explained that they were not legally responsible for Hertz in SXM. All's well that ends well but a lesson learned.
