The 3.5L Explorer EcoBoost is a fantastic combination. We bought one for my sister last winter, after a couple years of trying just about everything. We did a lot of research prior, and there's really very few complaint. There was those report about CO and exhaust smells a few months ago, and from what I can tell, this only happen if the trunk isn't fully closed and the HVAC is in recirc and you're idling for long periods (there may be some merit to up-fitters removing grommets and even air-balance flaps as well).
I do think good oil is a must on the EcoBoost motors. Ford requires full synthetic in every other market they sell them besides the US. In our 1.0 Fiesta, full synthetic nets about 4 extra MPGs highway. Plus, the more stable VOCs in synthetic oil should reduce carbon buildup.
That all said... Have you considered a Flex? It's like an Explorer but with more cargo space and better handling, and IMO looks better;)
