Hi,
The front bumper hanging off the corner like that would,nt worry me to much, mine was perfect when I got it and mine is doing the same and has not been knocked, its come out of the bracket or the bracket is broken, very cheap to replace from MB and i believe its the same bracket as the smaller standard bumpers so i believe it could be inherent weakness as plastic gets old it gets brittle, rear bumper alignment is the same as mine.
Wiper problem (very common on a 202) would not stop me buying the car but i would use these things to negotiate a better price.
The seat and the steering wheel i would want too see better pics, as i would be concerned over the accuracy of the mileage shown.
But the above problem aside it does look like quite a clean example and a nice colour too.
I liked those style wheels and was gonna buy a set for one of my W202's, but now seeing them on a w202 I,m glad i did,nt buy a set.
