how/why would the upper control arm be like this on a 420SEL (picture)

[WANT '71 280SEL]

My family is looking at a 420SEL and one of the problem other than the fact that it "misfires" the right front wheel he said leans it a little, but not noticable unless you look for it? Anyways, he sent us about 30 pictures this afternoon and this one of them. We have not seen this car in person, my dad spoke with him on the phone, and that was it.
