W124 suspension is too soft- just look at them leaning when changing lanes at speed

Needs 1" shorter springs, better shocks and anti-roll bars, potentially a strut brace and you're sorted, though. Best Merc ever that makes most sense is the W128 IMHO. So well over-engineered and everything is so.. in place somehow.
Problem with the cam on this car is that it snapped while in motion, not that it needs replacing. Fella still hasn't got it home, thinking about it I might go and give him a tow to his place but we'll see.
