My suspension lasted to 200K miles, but between 200K and 215K all of the bushings and ball joints went bad. I'd look at all of them and check for torn ball joint boots, cracked bushing rubber and excessive play. If you want to keep the car a long time replace with Lemsforder (best) or Febi parts. Prices vary wildly depending on where you shop.

Other things that needed attention in that span were the ABS control module (replaced with a rebuilt unit) and several of the ABS wheel speed sensors. And clean your sunroof drains.

Hope this helps.
