95% of my stuff was purchased new. Sometimes, I buy something, and don't like it...price mine lower to help insure a sale.
I enjoyed the original hunt for the piece, enjoyed buying it, owning it (for a time), and had some enjoyment in the anticipation of possibly selling it.
A bit paraphrased, but I could not agree more, although almost none of the stuff I buy is new. I enjoy buying, owning, holding (just to look at and understand its scale and dynamics) and then selling (some items). I also enjoy finding a neglected piece and making it run or work again. I need to learn more, but that gives me tremendous satisfaction. As such, I like post-war trains the most, but have a handful of newer items. Ironically, I like SCL, ACL and Southern (post-war railroads), but most items made with those road names are more modern.
