Shared Parts - 02 ML-320 vs 04 ML-500??

[adplusone]

Finally got some response out of MBUSA on problems (accelerator hesitation and a transmission that downshifts at will) on our 2002 ML-320. They are going to pay off our lease (14 months left out of 36) IF we move into another MB product.

My wife really likes the ML (when it is working) and it is her daily driver. My question is this:

How much does the 04 ML-500 share with her 02 ML-320 in terms of mechanicals that could have been the cause of the problems?

Thanks!
