Scott I used to think that way. I remember thinking what a cool collection of pieces my '89 K3500 was and how I would use them if it were ever wrecked.
Then some little chickie texting instead of watching where she was going (if you don't hear anger in that sentence please know it's there!) hit me and totaled that truck.
I kept the salvage, sold off the usable stuff I didn't want for enough to cover my cost, and have some nice parts to use on future projects.
But I mourn the loss of that truck. I'd sure like to have it back. And I basically hate the replacement truck. It was a mistake.
Since then I've been much slower to think of things I like driving as parts cars.
