Not too bad, remember the NGT has a back up camera (unless you have a 17 Comp car). The side mirrors are actually pretty good. On the flip side, if I ever leave it anywhere (rare) its off in the middle of no where in the parking lot.
Having driven fire trucks and cargo vans for many years, using the skill of side mirrors to back up is the quickest way for me to back the new and old GT up then I transition my focal point to the rear camera (or open the door and look backwards on the 05/06) to get my distance to the parking curb/wall. It becomes second nature if you drive the car frequently.
Rear cameras still don't work for me in terms of side-to-side placement. Much easier to use side mirrors and a quick turn of the head. Rear camera is great for not smacking the splitter against curbs or parking blocks in the final few inches of backing up, but otherwise it doesn't help me.
