I'm not really sure, but that does seem to be the trend. You could
always email them and inquire, but that chances of getting an email
back are not very high.

Which KBB price are you talking about - Retail, Trade-in, or Private Party?
The KBB private party price is often lower than the price people ask for,
but I suspect it is in line with what people are actually getting. Most of
the free pricing services reflect inflated prices because they are based on
inflated trade-in prices, surveys of ads, and asking prices, not actual
selling prices. As for Ebay, I watch those auctions pretty closely and less
than 15% actually result in a sale because the sellers set too a  high an
initial bid or too high a reserve price.

If you want to know the true wholesale value of a car you need to find
access to the auction price book (sometimes called the "black book"). The
prices in this book are based on a survey of  the prices paid for cars at
wholesale auction. The NADA "Blue Book" retail price is probably the worst
source of "good" pricing data since it primarily reflects the prices used
car dealers wish they could get a for a car.  Think  of it as similar to a
new car's MSRP. The "Blue Book's" trade-in price is also inflated since it
reflects the artificially high trade-in prices dealers quote when making a
deal.
