My car doesnt feel stable when I drive 100. And I want to drive 120 comfortably (going to Germany). I guess this must be suspension not being 'good' any more. The car is 12 yo E Class W211. Mileage 45K. I would appreciate if someone points me in a right direction. Perhaps diagnostics with a good specialist. I live in Harrow - so NW London, Middlesex, Bucks, Surrey are good for me. I would however try to avoid MB dealers as 100+VAT per hour is expensive for me.
