I had well over $20k into mine, Stroker, new transmission, Alloy shafts, rear disk brakes, gears, ARB's, tires, wheels, winch, everything brand new. I had it listed for $6500 for over a year, ended up selling it for $4250 because I didn't have room for it at the new house. I don't feel like I took a $16k+ loss on it, I sold it for what others valued it at, at the time.
Like Pete said, I regret selling it, and want to replace it, but can't justify spending the same amount, or more on one that is stock and needs work.
