The below post is where I think the market sits for 1LE's. This is a 2SS 1LE that sold for $50K.

I see other posts at higher prices, and their not getting much interest. Likewise, the 1LE's online priced high have been for sale for a while.
I think some overpaid for used cars they need to sell, and some are not eager to let go of the market that used to be, and still hope to get top dollar.
