I have been looking at the 2009 Nissan Murano, Mazda CX-7 & 9, Subaru Tribeca and 2008 Nissan Rogue. The RDX is just right for me. All those wonderful luxury features plus not so huge. It drives really stiff, more like a sports car and the seats are wonderful. I made the right decision for me.
The side mirrors that angle down when you go in reverse. Also love the seats.
Not sure I could think of anything but maybe an electric lift on the tail gate.
