Well, having replaced pretty much all wear & tear parts in my rear suspension with MB star OE parts I have tentatively come to the conclusion modern life has more than it's fair share of low standards (or better known as aholes.)
Here's why:- My ride is still not where I expected it/want it to be and not where 140's were when they left the showroom/ sindelfingen.
My belief is that e.g. the replacement bushings, and other MB parts are just not as good (NO WHERE NEAR) as good quality as the bushings, and other suspension parts made in 1992 - 99.
Either that, or I am too demanding. Maybe so, but I have driven a few great 140's. The problem is I have now heard from several techs that MB parts are not what they used to be. Made in god knows where by who knows what...
So what to do? Unless you can find a late 90's CL with super low miles how can you get that old feeling back? Jeez. the modern CL rides only acceptably anyway.
This is a SERIOUS issue, If my hunch is right that modern parts are inferior when compared to140 era parts, what is the point in buying a classic 140 coupe and restoring it? NONE. you might as well go buy a shoddy 221. or even worse a 220

I drove a new c class recently. It wasn't a Mercedes, it was a dog for aesthetically challenged peasants with fake body parts

. Every bump in the road could be felt, waaaaay too much.
So, I have spent part of this evening looking at Rolls Royce and bentleys. But they are so ugly... and yes, way too costly and ostentatious for such monstrosities.
Anyway in case I am wrong (I'm not averse to that...) I will continue on and now repair the front suspension with OE as perhaps then it will ride as I remember a 140 can. So the rear is done, but I am losing patience.
My apologies for the Grrrrrrripe
