c-20 value

[BowTie Trucks]

I found the forum some time ago and today I joined! I used this forum a bunch when I was freshening up my c-20. I own a red/white/red 1972 camper special with 51k original miles (I am the second owner). I recently freshened up the original 350, repainted entire truck, new carpet, seats ect. The truck is in what I would call excellent condition, the paint is perfect, there is no rust at all, I added a new front grill, rhino liner, new chrome bumpers. I have a good friend whom loves the truck and offered me 12K for it. I really have no desire to sell, but I would not mind another old truck project. Is this a fair price? I welcome your comments. I would post a pic, but my camera is MIA ( I lost it). Thanks!
