I enjoy the smooth ride and the technology advanced features. I got all Navi and RES on my MDX because I didn't want buyers remorse. And, I must say it's worth it. I've had mine since Aug 05 and love it. Navi has been reliable when I input addresses, but not as reliable with directory assistance.
XM (addicted to it now) OnStar (nice discount on insurance) HFL (cell phone link is awesome) Navi with Back-up Camera
Rattle in rear passenger window and speaker is spoken about on message boards. I would've expected a known issue to have been fixed by Aug 05.
