I get really confused from alot of what you guys say. I am an american simpleton with an 89 190E 2.6. I don't compute km/h. Sorry guys . I have not tried my topend out and probably won't try to go over 120 on american highways.Also I have some problem where getting up to 70 and 80 miles per hour is shaky yet driveable but going up to 100 is just terrible. I'm trying to find anyone else who might know about such a problem But I am very fascinated with your stories. Europe sounds like quite an adventure. I would love to rent a new benz and cruise up in the 160 mph range.
