I saw that very auction in the OP and it started out real low ...like 20 dollars when I first saw it ....when an item goes that high and generates that many bids ....I cant help but envision in my mind the seller's buddy bidding it up.
Very well could have been shill bidding. Time will tell if it was an actual sale or if it will be relisted in the future.
If a buddy just got into a bidding war with a actual live buyer...and the actual live buyer won the auction... it's a real sale. Emotions may have got to the buyer.
One sale on ebay does not dictate the going market of a part.
