We have had our 05 Touring w/Nav MDX for four months now (all winter) and absolutely love it. For all out traction in mud/snow, this one can't be beat. Solid as a rock and have had not one single problem. Voice activated Navigation is absolutely amazing. Looked at the RX and X5, both were way overpriced and gas mileage was worse than MDX. It's time for an MDX Hybrid.
Voice Activated Navigation, All Wheel Drive, Bluetooth wireless.
Fix the control logic for the A/C, Make the roof rack optional (never use it).
