The price is a little high, but not too far off...
KBB puts it around 4k in "fair" condition, $4500 in "good" condition for your zip in Fresno.
However, before you sign the dotted line in a 2002 with 160k miles, just know that this is the first year of the 3rd gen, with infamous issues with the drivetrain. Mainly in the transmission, differential(s), transfer case, etc.
At 160k miles, I would want to see first of all...a CARFAX. Also an OASIS report if you can get it (Ford's internal service history record showing every visit it had at a ford repair shop with detailed accounts of service performed). Some basic things to check would be noises while driving....most notably if there is transmission or differential "whine", usually starts around 30MPH and up...the vehicle should not be loud inside. You will see numerous posts on here (including from myself) about diff whine in the 3rd gen's (2002-2005), it's extremely common, especially in the 4x4 models with the limited slip diffs.
I would also check the ball joints, this can be done in just a few seconds. Visually see if there are cracks in the rubber boots on them, or if they look very dry. I would also want to check the wheel bearings, this can be done by jacking up the vehicle and see if the wheel has any play when you tug on the wheel/tire.
There are so many other things you can check....or have a trusted non-biased mechanic check out for you. This guy is asking more than top-dollar for the SUV, it should come with lots of paperwork showing regular services, and also replacements of parts. 160k is a lot on an engine/drivetrain....personally I would stay away at that price. Or if you do go for it, don't pay more than KBB "good" value for Private Party...which is around $4500 in Fresno CA
