span

Hi all, I'm wondering what the effective lifespan is of factory fitted struts and springs? My R129 is really starting to rattle and bounce alarmingly when driving over rougher country roads. I know that the staggered 18 inch wheels don't help and I'm having some suspension components checked...

Not that I need one yet, but I am interested in the typical life span of a Mercedes exhaust system on a C class, or other model.. Milage / year of car etc. How long is it expected to last ? Anyone ever had to purchase one recently or in the past ? I bet that this will bust the bank.
