I shopped for about 5 months for mine. 2000 sport 4x4 and it's in So Cal. I paid 6K for her and thought it was a decent price for what I was getting at least out here.
So Cal prices are higher than the rest of the country for sure because mostly they're rust free, ALTHOUGH... I saw a lot of nice looking trucks on the top that were rusty underneath as sellers have figured out they can buy crappy trucks from the rust belt/east coast and drive them out here and sell them as CA trucks to those that don't know and make a few thousand per truck. And a lot of them were from transplants too out here so finding a true CA truck is little more difficult.
