My wife really liked the Acura's size and features. When we first got it, it certainly was smooth and quiet; much more refined than the 1996 Grand Cherokee we had before. It was a good size and she loved the touchscreen navigation. It was a little disappointing that the MDX didn't have some luxury features that the six-year old Jeep did, like automatic headlights and day/night outside mirrors. Overall she and I liked the car. The trouble started at 37000 miles when the first transmission went out. It was replaced. It broke again and was replaced at 87000 miles and we discovered this is a well-known and chronic problem with Acura's transmissions. I cannot recommend early decade MDX's.
The navigation system, the rear space. Engine was smooth and quiet.
