Have completed about 1000 miles in the CLS500 and in Comfort setting very nice ride no complains. Thought I would today try Sport mode and see what the drive is like. It seems a lot smoother and a better drive or is it a physiological thing SWMBO said she could not tell the difference between Comfort or sport. How do other members feel and what do they drive in for a say motorway trip or other road, seems to excellerate better, I suppose thats the sport mode. You may gather this is my first Mercedes so feeling my way.
