about the rear-view....you dont need to even use it. the mirrors are large enough for you to see behind you...and if youre backing up just stick your head out the window. i've been doing that since i bought it in '99 and i havent hit anything yet (knock on wood). but the mirrors should be sufficient for you to check out cars behind you if you adjust it just right.

rear seats...my friend who is probably 300 lbs fit in the back...just takes a little practice...tell them to step one foot in first and then shimmy their way into the back...puahaha. i always take people in my car and big guys have fit int he back pretty easily b4...you just have to go in sideways.
