marketing
I've followed the collector car market for many years. Interesting how this popular car auction works. Say you're a dealer/retoration shop specializing in a particular model. May be street rods, Italian exotics, big block Vettes, Shelbys, etc. Doesn't really matter what as long as the model is rare and you have inventory. You consign one to the Barret-Jackson sale then bid it to the moon. Granted you've lost money on the commission. But here's the bonus, you've now set the "market price" on your inventory, and displayed a demand for that model.
It's all smoke and mirrors.
