Well the family DD Ford Flex is looking like it needs replacing so been looking at replacements. One that kinda ticks off the boxes we are looking for (AWD, 6 passenger, not a minivan or station wagon, diesel) is the Mercedes Benz R350 BlueTEC.
Considering the 2010-2012 but I can't find a lot of anecdotal reviews online. More than anything we are looking for reliability as our first year Flex is giving us a lot of issues as it ages.
How is the R350 diesel for the home mechanic to work on? How does the BlueTEC rank for reliability? I do all of the service work on our fleet aside from warranty/recall work. I wonder how they age (up to 300K).
