The thing that's really lacking in the 126 suspension is the sub-frame mounting design. It does a terrible job of isolating road chop and chatter. This may actually be desired by some as road feel. Personally, I don't need it. Here in California we have little warning bumps separating the lanes. These little nubs can rattle your teeth in a 126. While in a notoriously overly-stiff 94 Saab 900s these lane bumps are barely there. Little bumps and road chop are not really handled by shocks and springs; it's almost completely up to the rubber between the body and subframe to absorb and quiet these choppy little bumps. I love my 300sd, but honestly the 126 is completely sub-standard in this area.
