Heres my two cents, I dont have much exp with the ML but I had a 2001 CLK-430 and after owning it for less then a year, I watched it gobble up over 14k in warranty work. It only had 7k miles on it when I bought it and it was stuck in the shop every other week. Sad to say but I will never own another MB as long as I live.

I am sure I got a lemon or whatever but my boss didn't care what the reason was, he just got sick of me saying "i have to go to the dealer and drop off my car".

After that I picked up an 02 Jag XJ8 Super and its been flawless. Last week got my first BMW (CPO 2006 X5 3.0) and hope the experience will be similar. I am loving it so far!
