How do you guys determine the value of used cars? I know there are a lot of variables, but in the past I've looked at: Edmonds True Market Value (TMV) (some say since it uses county records it is a bit low since some of the deals are between relatives Kelly Blue Book (KBB) which I have always thought to be too high, partly becuase I have read it favors more dealer transactions, thus is a bit inflated. Friends in the insurance/salvage industry laugh when they here people use this. NADA is supposedly what banks use, and is often between the top two. I haven't used it much though. I don't have access to the black book since I think it costs, or the manheim auction reprots (which is just for car dealers). In the past, Edmonds TMV has served me well, I've usually been able to get better deals than what it says both on buying and trading in, but I've always used it as a guide. But for these Thunderbirds it is odd. TMV is at times higher than KBB, and most listings I come across on cars.com, craigslist, and at dealers are considerably higher than either. Unless dealers and private parties are haggling down 30% off listed prices, who is buying these cars? What we want is a car in good to great shape with less than 70k miles. All the books say this should be able to happen for between $10k-$13k. Yet most of the listings for such vehicles start out at $15k (barely) and are mostly $16k-$21k. A mint bird with sub 15k miles I'm sure goes for a lot, but how are the pricing sites so far off from what I've been able to find for a 2004 or 2005 with 60k miles?
