Hertz was always bad at this anyway. For me the final straw was turning a car in and the guy recorded damage. I stayed there for several minutes making him point and describe, shining flashlights at angles, and was never able to see the damage.
It was one of the few times I got the damage waiver so I didn’t actually appeal it. If you get Hertz, definitely get that coverage: you’d be a fool not to. And factor that in when comparing prices with other rental companies
