Things I wouldn't mind having:
- smoked headlamp bezel
- 18" rims (though it only mentions the Limited, so I assume it's n/a on the Sport)
- reinforced center pillar (though I haven't really noticed it as a problem in the 03-05)
- miniplug for an iPod (OTOH, I don't own an iPod)
- MP3 capability
- power seat
However, none of these would be deal breakers for me on a good deal on an '05.
I'll wait on a final verdict for the new appearance, but the round foglamps in a squarish opening will take some time to grow on me. Projector headlamps are cool, but the current headlamps work well enough for me. I'm not a big fan of a lot of chrome, so the SR5's chrome door handles and license plate garnish may be too much for me.
I thought I'd miss not having a power seat (since my Highlander had one), but I'm the only one who drives my 4Runner, so how often does one need to adjust the seat anyway?
It's interesting that they took some things away -- the trailer hitch on V6 models, the tonneau cover on the SR5, the cassette player, rear-seat audio, etc.
All those upset about all these enhancements that are on the '06, but not the '03/'04/'05: relax and consider that most of us have had months, if not years, of enjoying our 4Runners. Over the last three years, the 4Runner hasn't had a year where it was a complete carryover. If you kept waiting for "next year's" model, you'd never buy one.
