You are correct, eBay and Craigslist has replaced the good ole swap meet, but I remember 25 years ago I thought I had the world by the tail because I had some rare part, double hump heads maybe, and then after online sales you realized your rare part wasn't so valuable after all. I also remember rows of new parts vendors at NSRA events, now it's a 1/4 of just 10 years ago, one vendor said he can't compete with online sales and wouldn't come back. But we use to have customer service before wal mart also...
