Okay, I guess I should have given them an extra $5,000 when I found out the car was numbers match. The options were very obvious, AM/FM stereo, air, power steering, power brakes, power windows, tilt, power top, tinted glass, power antenna, 400...all were installed and visible. The car was advertised in a multistate publication, was available for inspection, and was on the market for a couple of months. Apparently "the market" eventually found someone, me, the buyer, who felt the price was appropriate. If some cars get better hype and exposure from auctions, eBay, or online showrooms, that doesn't make them any better or different or more valuable, just possibly more expensive.
