E420T suspension, when to replace?
as a newbie here, let me first say that this forum is fantastic! this is how the internet should work: people with similar interests coming together, discuss those interests and helping each other out in a productive way! great

now, i just bought a '97 E420T Avantgarde model, 112tkm (68tml). how do i know when the suspension is due for replacement? kind of hard to tell as i do not know how the ride developed over time, and whether today it is very different from 2 years ago.
the front is feasible, the rear suspension is auto-leveling and quite expensive.
thanks for giving some pointers, "symptoms" to watch for, etc.
