We were taking a trip with 6 adults and wanted a large GM and ask several times if it would be a GM. Got sort of an assurance. Picked up a Ford Expedition. The front windshield was so dirty you could barely see thru it on
the passenger side. Dog paws and nose prints. Then it had no windshield wiper fluid.
When we returned it the manager was very apologetic an offered $200 off the rental price. We felt he understood the problem.
