I rented a car from Hertz for a week. When inspecting it before I left,they noted that there were some scratches on the mirror. While I was driving on the highway I saw the mirror start to wobble I pulled over and it fell off.Nothing happened to the car in my care,I am sure that going 65 on the highway for 1/2 an hour dislodged it (it's cracked on the inside)as I never drove above 35 in the city. Should I call them and complain or rent again and take their daily coverage and return it afterwards? In my defense the check engine light was on when I got it & they don't usually rent out cars with that light on,so there were problems before I got it.
