This vehicle is incredibly fun to drive. I traded up from a TSX and the RDX actually handles/drives better! The SH-AWD system is amazing: I feel glued to the road, no matter how hard I push the RDX. Acceleration is great, and fuel mileage (for me) has been adequate (21 mpg) - not great, but decent for a SUV with this kind of acceleration. The interior is wonderful - comfortable, tasteful, high-tech, full of useful information. Awesome stereo system. The nav system is very user friendly, if a little outdated in its database - but I absolutely love the XM live traffic display, which saves me time every day. Great vehicle!
Handling, grip, acceleration, interior comfort and space, navigation (with live traffic), sound system, moonroof, bluetooth, good looks, compact size.
Update nav data more frequently, slightly improve brakes (good feel but a bit sluggish), add rear AC vent. (I thought I'd miss an auto rearview mirror, but the rear window tint is a perfect substitute.)
