Most R129s use conventional shocks and springs, which sellers cite as a reliability plus with no expensive suspension technology to fail; adaptive damping and/or air suspension (ADS) were reserved for the 600SL. Age-related bushing wear is the main suspension concern, and some owners lower their cars on Eibach/Bilstein for stance.
Suspension: simple by design, adaptive/air only on the 600SL
