I LOVE the Acura MDX... I have been researching a lot of cars, and it is great to have a third row, but the MDX's third row is just not a convenient if you have two car seats in the second row. Other cars (alternative to minivans to have better third row access) include crossovers such as Buick Enclave (I was impressed with the test drive!), GMC Acadia, Chevy Traverse. These non-minivans have captain chairs in the second row that allow you access to the third row. There is ROOM behind the third row as well. There are probably more than I listed (http://research.cars.com/go/crp/buyingGuides/Story.jsp?ye....
In the end, I think we are going to buy a MDX because I looove the way they drive. I don't think we need all of the room of the crossovers and minivans for most days of the year - only on long trips. So, I think the question becomes, how do you want to use and access your third row?
Well, that is my two cents!
