Your best bet is to keep until the wheels fall off. KBB may show its worth 50k but you can buy a used 2005 4.4 for $52k, so I dont think kbb is even remotely right. The car without the mods and 45k miles on it has real street value of about $37k. I have seen some for even less with less miles. It is feasable to ask a 10k premium for the mods, but anything other than that is unrealistic. Based on what you have done, you should consider keeping it. You have one of a kind and should enjoy. There arent too many vehicles out there that will touch it and if you sell...I think you would regret it.
