The driving experience is definitely different. The MB is more like a car than a guided missile.
We service lots of MLs and a few GM suvs. Other than balancer failures we have had great revues from our ML owners, including my wife. She bought hers new in late 98 and has 40k on it now. Its been out of warrantee for two years and so far nothing has failed.
