So I bought a base GT because it was a can't miss with timing. Wife was in the right mood most importantly. I really like some of the premium options, and I am wondering how difficult it would be to add some of these. I have a junk yard locally that specialises in late model Fords, and he is looking for some 2011+ Mustangs. Would it be possible to get a SYNC set up with the head unit and premium steering wheel to "plug and play" in a base car? All of the wiring should be there correct? Also interested in OEM HID's, Power seats, and the illuminated door sills.
