Look at one of these for a DD
The fuel mileage on the 320 is comparable to the 430/500: Go for the V8

Sorry I missed your post. We've had the ML430 since 1999. During the first few years there were a few things that went wrong that were covered under warranty and a few that occurred after the warranty had expired. The biggest things were fuel sensor is broken so the gauge only gives you an accurate reading sometimes, mass air flow sensor, window switch unit in front, D pillars cracking, but nothing too major in terms of reliability/ drive-ability. During the last few years there haven't been any problems at all. It's been used on numerous road trips down the coast to California, Nevada, up the coast to Canada, and it has been extremely reliable. MPG for me is 15 and that's mostly city driving. MPG on road trips isn't much better at around 16-18 (but closer to 17).
It's also very good in the snow and has never given us any problems.
My uncle has a 2003 ML350 and his MPG is right around the same as mine. Albeit he lives in San Francisco where there's many more hills, but Seattle is also quite hilly. When I drove his car and filled up, I only netted around 15.5MPG. I'd definitely go for the extra power of the V8 if you can. Something else you may want to look into is a 2003+ ML with a 6 gallon bigger gas tank. I have to fill up every 250 miles, it'd be nice to not go as often. I won't say the V8 is fuel friendly but more like the V6 is a gas guzzler. (Maybe just go for the ML55? I find the ML430 although will get up to speed, is a step behind when I press the gas pedal)
For our family, we have simply outgrown the ML. On road trips now, we're carrying 4-6 full sized adults at any given time. There's simply no luggage space behind the third row. The car is simply too small. Heck, the car is .1" shorter than our CLK W208!!! (so same as your W203 C) With three rows of seating there also isn't much leg room for the back two rows. It really depends on how many people you have to carry and how much room you need, which is the reason why we just got an R, probably the best road trip car for 6 people.
