i've been using ebay for over 2 years and i've noticed that there seem to be trends in pricing. when i first started looking for headlight doors for a '71-'72 mach 1 grill you couldn't touch them for under $65. now they are all over the place and you can get a pair for under $20. it seems the vultures spot something selling high, buy as much as they can and then start to list, driving down the price. it takes a little while to happen, but i've seen this happen on a few items i've been looking for.
