NADA, or any other book doesnt buy vehicles. Most of these books value 4 door classics higher than 2 doors. And modern cars with manual trans less than auto. Doesn't fit the reality of the true market. You may end up putting a bunch of money in to the truck and still only get $4000. 4k for a clean truck in my neck of the woods would be a steal---rust free trucks in NM arent that hard to come by.
