I leased this car last month, and am generally pleased so far. It drives well with nice power and handling, although the ride is a little bumpy, if you are used to a luxury or performance sedan.
The power and handling are very good; I had an Audi A6 wagon, and I think the acceleration is just as good in the Acura, if not better. Also, the voice command / nav system is very impressive as well.
The gas mileage is not very good; my first two tanks I averaged about 19 mpg (which is probably good). Also, it needs premium level fuel, which will add to costs over the lifetime. Seating for my kids in the backseat is just OK, not as much room as in the Lexus 350.
