Looks like you have too much negative camber.
These are special camber adjustment bolts that can be ordered from your MB dealer.
Any good alignment shop should know this, they are the experts and should be able to figure this problem out.
Double check the parts numbers installed against what http://epc.startekinfo.com/epc/
states for your vin number.
You also need to check the ball joints and inner and outer tie-rods for wear. AND your lower control arm bushings. Again a good alignment diagnostic shop should be able to identify worn parts.
