Crashed GX can be had for somewhere between $3k to $10k depending on how bad it was smashed. For example: http://erepairables.com/salvage-cars...gx+470-4670255
(and boy is that one tempting...talk about cheap wheeler. Flares and steps are already removed for you!)
Body is somewhere near 10, then plan on spending another 10 on bumpers, headlights, sliders, and all that misc junk to make it complete. So, yeah, you could buy a Wrangler Unlimited Rubyourcon and spend the next two years driving instead of building.
