I paid almost exactly the same money for both of mine. The '06 does have the side impact airbags and an "oil change monitor" which is next to useless.

The '06 models are available with step bars and moon roofs, neither of which do much for me.

I am surprised there are any new '05 available. If they are discounting them that much they want to move them. Work a good deal and then ask the salesman about the anti-theft system. Then when he admits it has nothing but the "perimeter alarm" try to get him to take more off. That is my only major disappointment with the '05 is the lack of a passive anti-theft system. If you do end up with an '05, don't let them B.S. you about needing $50 keys, either.

Good luck with the decision making.
