I've caught a post in another forum about early problems with the ML55, (oil leaks, part replacements, cheap interior parts, etc.)

I was at the dealership a year ago picking up my ML320 for A/B service, when a black ML55 pulled up, and it had all of the window dressing, including chromed AMGs. I nearly crapped my pants when I saw it. I know my wife would have beat it out of me if I considered trading in the ML320 for one of those hot rod SUVs.

I was a little disconcerted when I read that post, that they are not really up to par. I know about the inferior plastic interior parts (but my trade-in was a Honda Passport, so I was still a quantum leap up), but what about the rest of the problems? I am happy with my ML320, but I still get "ML55-envy" whenever I see one...
