I'm about to part with my 124 92 300E (112k) that I've owned for eight years. I'm considering either a 2002 or 2003 ML320 that have in the mid 60k miles on. Both are one owners and a per service records have been well maintained at the prescribed times. Will I be disappointed from the comparison of the comfort and mpg that my 300E has provided me. I've read/heard that the ML rides like a truck and enjoys premium fuel. I consider myself a sensible driver and not one with a lead foot. Over the last 40 years I've owned MBs both gas and diesel. Since having owned a 92 Dodge Caravan I've been wanting to try the ML320. I would appreciate comments from current ML owners
