We rented a car from Dollar at the Phoenix airport. It was not a good an experience. Once we got downstairs and got to the car we carefully looked it over. There were dents and nicks in the paint and the windshield had a chip. My husband went back to the desk and asked where we could note these defects on the receipt and the person at the desk said"oh you don't need to write that. We consider that normal wear and tear" when we insisted they make a note, they reluctantly did.
Good thing because when we returned the car the checkin person would have charged us $$ for the defects if we hadn't had the notes signed by the other employees.
The car ran well but was filthy. Would rather rent from someone else. Not a good experience.
