One of active forum members put those on his W210 and claims this is the best buy without going into high prices.
I was able to find "affordable" monoblocks and those are hard to beat. Picture in profile.
Coming to rim sizes, I bent 16" on Los Angeles potholes.
My wagon originally come with 16" of the same design and not only they had lot of scratches, but 2 rims had bends on inner sides.
I wonder if PO did take 4Matic as offroad invitation.
