Somewhat odd combination of choices. I can say of the Acura that the J series are very easy to maintain yourself until you get to the timing belt at 100k miles. Soichiro Honda had a requirement for his engineers that his cars be easy to work on for the owners, and to a great degree that still holds true today.
A month ago I helped a friend change the cabin air filter on her Nissan. It required the glovebox and other trim be removed (8 screws) and the filter was back behind the center console; took an hour start to finish having never done it before. To change the filter on my Acuras, no tools, glovebox unclips, remove a shroud covering the filter, slide it out, replace. Took 10 minutes the first time, 5 min the second. Point is, ease of maintenance is a design consideration at Honda/Acura.
