Loving the Bilsteins I put on my W126 two years ago now. They have broken in real nice and still seem like the perfect shock for these cars. Not a hint of any leaks or any wear so far.

I don't see any reason why a set of Bilsteins won't last 100k miles. At $70 each they are not that pricey either.
