We recently got a '14 MDX with AWD and Tech package. If you are looking for a new MDX, check around a few dealerships to see if a 2014 in the color and options happens to be available. We ended up buying in Greensboro since it was not available in Charlotte. You can get a '14 at or below invoice whereas they won't budge much on the 15's as of yet. There is literally no difference (other than the VIN stamp) in the 14's and 15's MDX's.
We love ours and researched the same vehicles you are. I would hold off on the Volvo for now as they are doing a complete redesign on the XC90 that should be available next year.
