My point is that there is no magic number that is the "correct" value. You can look at pricing guides and comparables to get a range of ballpark values, but in the end, it is up to you and the seller to agree on a price in order to make the transaction happen.
If you are a buyer, then the right price is the lowest one that you can get the seller to accept.
Obviously, there are a ton of factors involved that could never be taken into account by nada, blue book, edmunds, etc. For better or for worse, personalities and psychology often come into play when dealing with older used cars.
How bad do you want it?
How bad does the other guy want to sell it?
Do you like the color?
Does the seller need to move it before he leaves for China next week?
All of these things would potentially move the price, and every deal is different.
Good luck!
