Tips on Buying Cars: Problem with new car, mustang gt, different color

Question
Purchased a new 2010 Mustang GT 2 weeks ago.  When I showed up at the dealership to pick up the vehicle found a big dent on the driver door.  I was told by the dealership that it could be fixed by simply pulling it out and that no paint or bodywork was needed, I agreed for them to fix it that way.  They did the job and I picked up the car on a rainy day (couldnt see it clearly and it looked ok).  I now have washed and waxed the car and noticed that the door with the dent has a different color than the rest of the car, it was actually painted.  What can I do: should I ask them to repaint and fix the color mismatch? does the car lose value because of the body work and pint job? should I ask for a new car to replace this one with? any advice?  thanks

Answer
Julio:Your concerns need to be addressed to the management of the dealership where you brought the car.Buying a new can be great experience,or a bad one.To be honest,I would not accepted the idea of doing body work on the car,before buying it.It would seem,a another Mustang could have found or located.Keep in mind,Ford will send a survey of your buying experience,and if the survey is returned with poor results,the dealership will know about it.The point I am making:Total customer satifaction.Are you?
