Nada prices for squares.

[rs74]

How accurate are these prices compared to what the insurance goes by. I know that it depends on what the condition, miles etc. are. However on the high retail side of my 85 short bed C10 it lists $9502. For both my 84 & 85 K30's they list $8502 and $7720. Now neither one of these trucks are mint but was just wondering if they were then how the Nada prices would compare to the Insurance if it was totaled.
