I have thought this for some time but kbb and even nada and Edmunds are very low in my area. Example I've been looking at mustangs well an example is an 06 v6 manual trans mustang in good to very good shaoe, the average listing price is between 5-6k and people are selling them for 5 all day long. The dealer prices aren't much different than the private party prices but people are paying it. Kbb says they are only worth 3-4400. However I can promise you if I search for any for even 5k and under I will not find a single one within a 200 mile radius. Are these price tools just wrong? Or???
