I've watched some BAT auctions over the past couple years and prices have risen dramatically. Subaru's for heavens sake are being sold for $200,000-$300,000. Parts for cars on BAT are also crazy too. I have some parts that have tripled in value, if I were to auction them off on BAT.
However, the stock market has tanked, interest rates have risen and I expect prices overall to fall. I've actually moved all my assets into baby formula.
I do get eBay notifications for Kirkham's and I have seen some auctions/ads where the price is over $200,000, but I just thought they were delusions of grandeur.
