Damn. That does look pretty f'd up.

That said though, I have SO interior and in the winter wear jeans everyday. It stains fairly easily, and as such had to clean it pretty regularly (one a month). I have noticed, that on my drivers-side bolster the "piping" is starting to look a little worn. WAY more than my E60 M5 looked after 3 years. It is not as bad as what is shown in your second to last picture but if I was a betting man, I'd say it will in three years. To help prevent this, I am moving my seat back before getting out of the car and brushing against the bolster.
