Complaint Review: Enterprise Car Rental

Lexus dealer provided me an Enterprise Car Rental due to a recall.  Rented a truck for several months.  Got a small scratch on the door when I was parked in a parking lot.  Got a $200 repair quote from an auto body shop. When Enterprise asked me to re-sign papers after a month, they noticed the scratch and literally seized the vehicle.  I objected on the grounds that the rental was not yet completed and that I planned to have the scratch repaired prior to turning it in.  The location manager refused and would not permit me to speak to a supervisor.  I wrote to the CEO and got no response.  The repair bill was sent to me recently for $964. 

They charged $691 for the repair, including $156 for paint and $530 in labor.  Then, they tacked on $152.95 for loss of use (my auto body shop would take one day) and $69.10 for "Diminishment of Value".  Enterprise claimed that I had no right to repair the vehicle myself, and that somewhere buried in the multi-page, illegible contract there was a statement to this effect.  I would understand if a car was damaged severely or significantly mechanically damaged that they would want some say in the repair, but I believe that Enterprise's practices are predatory, unfair, and dishonest.  They should have allowed me to at least get quotes from acceptable body shops and to have completed the repair before turning the vehicle in.  They clearly are using this detail in their contract to take advantage of the consumer and charge 5 times what a repair should have cost.
