i don't think thats too bad for California..
Im in florida, I bought a 2007 sport V6 4x4 loaded with 79k miles for 16,000 last month from a private seller..
Now in addition, which I feel gets over looked a lot when people talk about what they paid for the vehicles, is the taxes and maintenance that immediately follows the purchase..
in addition to my 16k cash price..
I paid 1k for tax, tag, registration, and title fees..
and I would say I have spent between 1500-2000 on maintenance and upgrading and thats just the basics for most part.. (transmission flush, differential/ Transfer case flushes, greasing the drivetrain, new synthetic oil, oil filter, air filter, cabin filter, new plugs, tint, spacers, floor mats, cargo mat)
that is not including a few thing that were specifically wrong that you or I in this particular case missed at purchase.. had to replace a fog light, the rear hatch switch, and fan clutch..
so all in I got into a mint condition 4runner with 80k miles for 19k, (still needs a lift, some better tires, brakes down the road, and a touch screen navi.. but I will wait until the time comes...
Good luck..
