FWIW kbb reports mine as worth about $8300 for "good condition" on private party resale. Mine is an '04 sport with 90,000.
I feel that $8300 is a bit high, especially given the economy right now.
kbb describes "good condition" as thus:
Free of any major defects.
Clean title history, the paints, body, and interior have only minor (if any) blemishes, and there are no major mechanical problems.
Little or no rust on this vehicle.
Tires match and have substantial tread wear left.
A "good" vehicle will need some reconditioning to be sold at retail.
Mine certainly has no "major defects". The paint has pretty good pinstriping from offroading, so that's where I'd probably ding my price (pun fully intended).
The body doesn't have any dents.
There are no known mechanical problems, let alone "major" mechanical problems. There is no rust on my truck whatsoever. The tires have some wear on them, but they may need to be replaced by the beginning of next summer.
The interior is spotless with custom leather- aside from some scratches on the rear plastic swing gate jam from sliding some stuff in and out of the jeep. Carpets and headliner are unblemished.
Everything else is standard equipment for the basic sport. Stock sound system.
