Interesting valuation site.

You have to scroll down the page to find what you're looking for. However there were a few "concepts" that I'd never seen before. They've completely left out the 67-68 c-bodys, Dodge anyway I didn't check the Chrysler or Plymouth pages.

You have to find the year and model you're looking for then select the Valuation tab. Interesting to see how things have gone back up after taking a dive. Note: I believe these are auction prices.

Yeah, I'm guessing auction results, likely from eBay at that. I turned my nose up at $8500 for my car once, I won't make that mistake again.

looks like they're using physical auctions like mecum and others;

The tool is flawed...
"1976 Chrysler New Yorker Brougham Cost, Valuation and Auction Sales Data
Average Sale Value : $6,050Lowest Sale Value : $3,600Highest Sale Value : $9,350Data based on 4 auction sales."

$9350 was a fluke...

They state they don't use the high, or the low price, just the ones in between. So they really base this one on two (2) whole cars sold at auction! This is why I take these with a grain of salt, they just don't reflect real world selling prices. They are fun to look at for amusement. And the worst thing a seller can get ahold of to help solidify their delusional thinking.
