Well this was new one to me.
Went to visit a buddy, who's the service manager at the local Chrysler dealership today, happened to be there when a car rental agent came to pick up one of their almost new rental vans that wouldn't start last week. Apparently the last customer who had rented it filled the tank half and half, (water and gas),to save a buck! Well, good job it was really cold last week, the water froze,still the total bill was almost 600 bucks...........
