It seems that every time takara reissues convoy he sells out and appreciates in value. I have been searching the convoy auctions on ebay and some of the prices are insane. I have a sealed book collection 00 that seems to be going for over $200 on ebay. That is nuts. I hope takara reissues him again, so I can buy him in a vintage style box for more reasonable dollars. I don't include any us reissued optimus's in the above thought because they have short stacks.
