Door replacement 2006 cobalt on 2006 Chevrolet Cobalt

Hello, I have a 2006 silver chevy cobalt LT. The door has been dented and I was considering going to the junkyard to find a replacement door as my dealer quoted me $1500 for repair. My questions are
1. Did the colour code change in the cobalts between years
2. Are the doors in the Cobalt and Pontiac G5 interchangable?
3. Is it possible to hook up the electrical to work with the Cobalt LT if I purchase an LS door?

Thanks so much for your help!

no, i do not believe they are
you gut your door and install it all in the donor door.

Your Cobalt is almost six years old. A good body shop will paint match the paint on the car.
The dealer is not the only place to have the dent fixed.
