Hello Freestyler,

I strongly believe there is no lifetime on most items on a car.
It depends so much of driving style, driving conditions, road and even weather conditions, etc...
On my W124 300TD turbo at 326000 km and 13 years old, almost everything is original except front shocks, tyres offcourse, one battery and after last Friday one new glowplug (cyl. No 4).
It's used under mixt conditions and I am driving rather quietly.
If your bushings are used so fast your car is in a need of a thorough check-up, at least for the drive train!
BTW are those AMG 17" really original AMG's , I am allways
suspicious to those large tyres...
Greetings,

Danny
