There will always be price fluctuations in old car parts. If you get two bidders who want the same part, the price will go up. I once got $225 on eBay for an average set of 67 Nova rocker moldings, about 10-20 times their California swap meet price. Two guys got into a bidding war and the price went through the roof.
