My turn (& first post):
In 1985 I bought my '37 Chev Pickup for $300. I got married soon after and the PU always seemd to be at the end of the list when it came to time & attention. I dragged it with us when we bought our first house (even though it was in pieces ;'}
Anything I could do for cheap (or better yet FREE!) I worked on. Everything else had to wait.
Then wifey decided that she didn't want to share the house, the kids, and the bank account, so out the door I went. She had the '37 hauled off for SCRAP!
Fortunately, our state requires "abandoned" vehicles be offered up at auction, so "won" the right to purchase my own truck back for $1100.
Two more times I dragged that poor hulk around until I finally got back on me feet and started the renovation - that's what brought me here!
