Thinking of selling my fd.

[bane]

In your guys opinion what is the best way to put a good market value on and fd. Of course i know that i can look up the value of the car per mileage and such, but what about mods? I have seen to much variation in the prices of modded cars with the same mods. If I do sell it i want to make sure that i have a good value so i don't lose out, but have a good price so that the car moves quickly.
