Purchased '10 MDX in June '10. Needed an AWD/4WD SUV >5 seats with tow hitch, priced under 50K. Also have '09 BMW X5 35d (diesel) which I love. First looked at another X5, but 3rd seat optioned vehicles were hard to find.
The MDX drives well everyday, has nice electronic things (nav, rear cam, bluetooth, ipod/usb adapter.) Rear seatbacks tilt back a few degrees making the difference between an okay seat (BMW) and a nice relaxing one. Interior space definitely bigger/more usable than in '09 X5.
Where the MDX really shines is its snow traction. This car is better on snowy town roads in the Tahoe area than my X5. Note MDX = Michelin Latitude tires, BMW = Bridgestone Dueler runflats.
Nice functionality on navigation and backup camera system. XM NavTraffic (subscription needed after 3 mos) is very useful.
Nice package pricing on electronics.
Reasonable pricing on tow package (dealer installed).
Excellent winter traction!
Pretty good power (not as much pull as my X5 diesel) but smooth. Inproved since the '07 model which I test drove which was not very responsive to throttle requests!
Excellent transmission: Well thought out gear spacing, paddle shifters invoke a nice quick gearshift which intelligently knows when to shift back to the normal gear (based to throttle position/speed).
Better gas mileage (getting about 20 on highways in the SF Bay Area.) Diesel X5 gets about 26 (as rated and in my experience) even though it weighs 700 lbs more.
Standard roof rails would be nice.
Headlamp washers are not even available (definitely need in the Tahoe area).
