Anyone have suggestions on how to determine a fair market value for an existing RV, RV8 in my case? NAA on Trade-a-Plane shows homebuilts for valuation, but when selecting Vans and year, "no models available". Can look at any number of ads on Barnstormers, TAP, here, etc. and get a broad range but want something more reflection of market specific to the model, mods, avionics. Thoughts are appreciated!
