I called my insurance company to inquire about coverage on rental cars. She said we didn't need to purchase insurance from the rental car company, but she said loss of use was only covered for Enterprise and Hertz. I thought Hertz, Dollar, & Thrifty were all owned by the same company? 
Do you think if I rented from Dollar or Thrifty, I would have loss of use coverage?
