Just purchased an '07 MDX with Tech package. The more I drive it, the more I love it. Takes some time to get used to all the buttons, features, voice commands, and the GPS system, but the car rides awesome, nice pick-up, and everyone just loves the look of the car. AWESOME!
I love the lighting in the car - everything is well lit, with nice colors at night. I love the fact that most every features can be customized to my liking.
Exterior temp gauge can only be seen by the driver. Only driven 200 miles, so mot so sure how it is doing with the gas mileage. Will compare to my '04 4Runner with the first few tanks. No other improvements that I can think of just yet.
