Just checked my car with a straight edge. The rear wheels are the same in both "toe in" and "camber", relative to the body, within 1/16" or less.

One inch is so extreme that it is possible to suspect the fender rather than the suspension. Possibility: there was shipping damage that was repaired to look good but the fender wheel opening is actually not out far enough.

Incidentally, while some factory workers may take coffee breaks, some also take (Porsche-provided) beer breaks. One supposes this is not allowed to affect the work. (Probably not true in Finland anyway. Don't know, have only seen Zuffenhausen)
