I dont take your post as picking a fight- I think we all understand the there are many perspectives shared here on "value" vs price; these are simply opinions. I respect yours.
There is a line where the emotional overrules the rational with these trucks.
Price: For the buyer, a 100 is worth what the buyer is willing to pay. But from a valuation perspective; what a bank or insurance company is willing to underwrite the value at total loss or replacement should be the reality check for its true "value". The delta between what you own it for and what insurance will pay out comes down to personal choice. Rational kind of goes out the window, and the emotional creeps in. How much loss are you willing to absorb for the "emotional" connection to owning/operating the truck? I'm not saying its a bad thing, but let's be honest about the rationale.
Admittedly, with all the mods on my truck, I'll never recover my outlay in a worst case scenario, but its my hobby truck and I'm having fun building it and very much enjoying the use of it (the emotional overruling the rational). The goal was to build a reliable overlander. My 05 was a no-accident, 1 owner truck, regularly serviced at the same dealer from day 1 until I bought it. Mechanically 7/10 Exterior 6/10, Interior 7/10. It had 160k miles and I paid $13,500. While I felt that price was a little high for this truck, it met the overall criteria for what I had planned for it for build budget and intended use.
I think 150k mile 06/07 models with no accidents and reasonably well documented service history are upper mid to high teens (16-19k) value range based on region. I certainly wouldn't pay over that unless the mileage was well under 100k and it was absolutely flawless.
