Love the MDX, it is very comfortable on the highway. We are averaging around 21 mpg in mixed driving. We bought ours used and have had a problem with the driver's side mirror rotating down in reverse, then not coming back up to the correct position. Also, after driving a Lexus RX300 the steering in this SUV makes the SUV feel heavy, not as nimble as the RX300.
Love the tech package and XM radio, comfortable seats, room for extra passengers for a short distance.
Heavy feeling steering, makes the SUV feel heavier than it looks. Driver's side mirror doesn't work right after reseting all options for it. Don't like to have to use premium gas.
I recently purchased a used 2007 MDX in like new condition and the side mirror does the same thing. If you put the control back to the center after setting the mirrors where you want them, they will stay put and not drop.
