We test drove an MDX and compared to most of the competition, the drive was much more car-like; however, I did not feel the full 300 horses (I didn't take it to 6500 rpms).
Our biggest disappointment was the 2nd row seat. Many parts are borrowed from the Pilot, but unlike the Pilot, the seat does not adjust forward on rails, and only the passenger side slides forward for entry to 3rd row. This is a major pain with little kids and downright dangerous in parking lots if they jump out on the other side of the car away from Mom.
This will likely keep my from buying a MDX... Sorry Acura.
