General Q, I currently drive a ml320, 136K trouble free. I am considering up-grading to a 350, or 500. I prefer the sport package look but can live without it. My Q's here: 1> noting the ml500's seem to have a fairly low resale value relative to there age / mileage ratio. 2 > ml350's seem to be just sightly priced under the 500's on adverage. * and 320's are just a hair lower that the 350's. ( vehicle years I am looking at are 2002 - 2004 )

Other than power, are there any real major differences in the 350 to 500's.

Is the only real difference in the power area. I live in Houston and want to use the vehicle to drive to Palm Desert area of Calif and back when I feel like a good drive to overview some business matters. ( may leave it there for extended periods, but I like to drive and think so need the option open )

As far as the 320 vehicle is fine. Just figure I will sell it now and up grade while the miles are not so so high.

Thoughts on this would be appreciated.

I will not be towing anything, pretty much just a day to day vehicle.

thanks
