Kelley Blue Book vs. NADA Book Values
I asked a loan officer once why they use the NADA book rather than Kelley Blue Book. She told me that the NADA loan values are about 5% more conservative (lower values) than the KBB. If the loan is defaulted, the banks have a better chance to recover their money. With lower loan values, the loanee (us) have to put a little more money down to get the loan. Conversely, when I sell a car, I always print the KBB values for retail and wholesale or trade-in, because I think the numbers are slightly higher than NADA values would be. Just my 2¢.
