I was following our SHO yesterday, and I noticed it is "dog tracking", with the front wheels tracking offset about two inches left from the rear. Otherwise, there's no indication of a problem; steering wheel is straight, there's no pull, and it drives fine. It was dealer aligned a year ago to SHO forum specs, front and rear, but I don't have information to know if thrust angle was checked. It has Ingalls adjustable rear control arms. My guess is the rear arms are out of adjustment, but wanted to check with the forum.
Last winter, my son was hit by a Yaris in the left side of the front bumper while sitting at a stoplight on a snowy street; that impact slid the SHO about two feet to the right. That was repaired, but alignment not checked as far as I know. He also curbed the right front wheel once turning right on a tight city street. So it's possible, I suppose, that the subframe was shifted or something else moved in the front, but seems unlikely to me since the alignment is still centered with no pull. It's rare that I'm ever driving behind the SHO, so I have no idea when this change happened.
Perspective is difficult to capture, but here's a couple of pictures:
