97 Cherokee has bitten the dust

My son, a 3rd year student at Montana U. has / had a '97 Cherokee
Country with all the bells and whistles. While trying to help someone
out of a ditch on an icy snowy road the jeep was smashed by a diesel
rig. As you may expect, it was totalled by the insurance company.

What should I look for as a fair market price for the jeep? It was in
good shape with upgraded rims and a brand new set of BFG KO's, had
power everything and the factory tow package, leather seats, etc. as
well as a six month old paint job. It had about 106k miles on it.

I live in SoCal so I think that is what they are using for the
location to set fair market value. I tried looking through the
autotrader but there wasn't a really comparable match for about 1200
miles from me.

Any advice would be greatly appreciated!
