My auto insurance with AAA covers rental cars, so I decline. Recently I rented from Enterprise and they surprised me with a new one: insurance to cover the loss of their use of the car in the event of an accident while it is being repaired, for the benefit of Enterprise. Cost was more than double the rental fee! I considered it a rip-off and declined. Since my AAA policy would provide a rental car should my own vehicle be damaged, I figured I didn't need it, but not sure. Having pre-booked a particular car which didn't seem to be available when arrived, I resented and detest the barrage of "up-sell" efforts by the agent and will probably not rent from them again.
