Paid $2100 in 1985 for my '46. Paid too much at that for a running (very poorly), reupholstered, repainted truck. Got all the receipts for everything I've ever done to it in the intervening 24 years, but I'll probably never add them up. It's now a "turn the key, step on the starter and go where you want" kind of truck. I love that truck - it's a hobby, not an investment (for me, anyway). I'd never get my money out of it in a million years. Don't care - can't ever see selling it.
The '51 GMC was given to me by my father-in-law; it was my wife's great grandfather's truck that he bought new in '51. Still working on getting it going, but the budget's a bit low these days. Sometimes those free one's can get pretty expensive!
