i think a fair price is a relative term. hopefully your friend didn't pay a lot for them and she will at least break even, which is better than anything you would buy new. i know you want her to get top dollar, rare is it a farm auction will do that. i have seen it many times though. more often i see people saying i could have done better myself. on a lot of those type of trucks won't even bring what they would for scrap metal. if someone bought one of these and parted it out and scraped the rest you could prob get at least $1000 each. that takes work and time and i bet it will be hard to get that at a auction. when you get a sitting truck you take a bigger chance and that iswhy they bring less. i have got 2 of my trucks for free and paid $1000 for my c60 it could have been parted out/ scraped for more and i didn't have to do anything much to it.good luck though, hope she gets a good price. hr
