Hi,
I own a 1995 S320, which I already replaced the engine wiring and throttlebody. Cars starting to run underpowered, thinking of just selling it.

I'm thinking of buying a S420 either 1998-99 if Benz had already stopped using the bad insulation wiring.

I also like to know if the 420's in these later years had any common problems?

Did the suspension come without the self level system?

Please post
Thank you
