good evening all

to start with , im new to the whole form based websites , therefore i dont know if im posting in the right section or not

anyway ,the other day i was with the mechanic who happened to say that i needed to remove my SLS and replace it with regular suspension system ,to be honest i have been driving this w124/e200/1995 for 2 years ,my father handed it down to me , and since then i have been restoring different parts and so ... anyway back to the subject ,the ride feels stiff and bumpy so im going to change them sooner or later.

my question ,if i may ask , how can i be sure that my SLS can not be restored , also what are the benefits of the "regular suspension system" , and how can i know the costs of either fixing the sls or changing it ,what are the best brands of struts ,shock absorber etc to install in my car ,keeping in mind i dont drive it aggressively.

would like to add another point ,he offered to install sachs absorbers ,but told me to ask at other places how much will it cost ,before he do so.

thank you all
