Should I complain to Ford Motor Company?

I bought a 2012 Ford Mustang in February of 2012. At the beginning of April 2014, I discovered a huge water leak that would saturate the floor of the drivers side of the car (front and back). I called The dealer that I bought the car from and they told me they couldn't see my car for a week. I made my appointment and dried my car, only to have it soaked again waiting for the car to be seen for its "appointment". Anyway, I brought my car in and it took them 5 weeks to get the car back to me. It spent two weeks at the dealership while they told me they looked into the problem and fixed it. Then they finally admitted they couldn't fix it and sent it to a body shop. The body shop then had the car for three weeks. At the 4 1/2 week mark, the body shop owner had said (after taking apart the whole front end of my car) that he had between 20 and 30 man hours in the car already and was no closer to finding the source of the leak. He then went on to say that he fixes one thing and it leaks from somewhere else. In the Next half a week, apparently they were able to locate all leaks, test to make sure it wasn't still leaking, bring it back to the dealership, have the dealership test it, replace the carpets, and clean the exterior (I'm very skeptical). I went to pick up the car to find out that there were 18 new scratches or paint chips in the paint. They know it was their fault because i showed them the car before i handed them the keys.

It is unlikely the car 2 years old suddenly developed water leaks.
There was probably an accident in the past.
Or was this warranty work?
Body work always takes time.
I'm not sure you have much to complain about?
I would have to see the size of the scratches.

Don't buy a Ford when Chevrolets are available. Go ahead and complain to FoMoCo - maybe they will give you another leaker.
