Only looking for dealer trade in values? Personal sale values?
Any dealership will try to work her/you over. That's just what they do.
If you're looking for personal sales, check out the 4runner forums. You'll have to do some homework, but that's generally the most "realistic" value you'll find for any vehicle. Would even be a good place to start for trade in values too - just figure that whatever you see on an enthusiast site will be slightly higher than what you should expect on trade in (and a bit less than you might get from craigslist, autotrader.com, etc).
