This Megatron is one of a kind. That the the most expensive Leader Class Megatron I have ever seen. The seller says that this toy came like that at a local Wal-Mart store so it is factory sealed. I requested more detailed pictures but the seller did not give them to me. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=140204681802&ssPageName=STRK:MEDW:IT&ih=004
It's obviously a custom, you can tell from the paint. The seller's lying, he did not find that factory sealed. (there's a possibility that someone painted it, and for some reason returned it) It's a pretty cool custom, nicely painted though no painted details.
Story definetly sounds fake to me. I'm guessing that they bought a Megatron, painted it up, and put him back in the packaging. The story is most likely there to try and make it sound like an extremely rare figure, when in reality it's just been painted.
