Which year model -which engine?
I do some...not-so extreme off roading with friends sometimes. I really havn't done it with any other SUV so can't offer comparitve information. All I know is that there is this pretty steep little hill that the 430 has no problem getting up, whilst my little engine whines to do it. I would def. go with the ML430 or the ML500. It is heavy and that extra horsepower will def. make a difference (I watch my friend's 430 with green eyes of envy!).
personally since I've driven both...I do like 500 more...the power of taking off and leaving everyone is a great feeling! but my 430 does fine too...
my 430 does 20-25 mpg on the highway, which is not bad...
And in my having also driven the 320/350...too slow for me...could barely keep up with the big guys on the road...give me power any day!
My Ml320 has been appraised at 14500 trade-in value...and its in "fair" condition. But it has less miles than the average 2001 Ml (around 10000 less miles). So I guess you could get yourself a decent 320 from 2000, 2001 for 15K.
