I'm not sure it's the market not being there but being lower. I know we all highly value our rigs and their mods but we get literally pennies on the dollar on the used market for them. You guys should scope out the prices on edmunds.com or kbb.com and go from there. Then run some searches yourself through craigslist.org and maybe autotrader.com to see what other asking prices are on similar Jeeps.
Just running the numbers on my own Jeep as an example (not that it's for sale), here's what I plugged in:
Full steel doors
Tilt steering wheel
Condition: Average or Good (I'm being kind to my own rig here)
Kbb = $9,600
Edmunds = $5-7k
I got dinged on edmunds because the condition was only average.
To the above I'm also running the following notable mods:
Rubicon D44 rear axle
Truetrac LSD up front
33" tires (new)
SwayLOC swaybar system
2.5" lift w/ OME shocks
Rear shock shifter mod
Belly-up low-profile skid plate
SYE / CV driveshaft
Sure, there is some nice-ish stuff in the parts list but I doubt I'd get much extra and would probably try to list my rig about $2k over the KBB price as a starter, say, around $11k and go from there.
Don't mean to rain on anyone's parade here but just trying to be practical: used, modified Jeeps don't command they money they should. Though I think clintrivera's rig could probably get a bit more than normal due to his V8 engine swap.
Best of luck.
* Depending on what my plans were post-sale, I might keep the Warn Winch and mount it on another rig.
