 I am very unhappy with the ride. MB should be ashamed, no wonder they are loosing market share like anything. What the hell were they thinking when they designed the suspension system for this thing - ML500 with $50,000.  The other problem, which my dealer tells me is normal - all tires are feathering a lot, he tells me this is normal. I am supposed to change the tires every 15-20000 miles?   My god the ride is just so bad - 10 mins ride and your body is ready to fall a part.  never expected a donut size tire either with MB, when others have full size spare.  Don't know what to do with this.
