Hello all, I hate to ask these types of questions; I know value of something be it a car or a part is subjective. I have a spare air flow sensor for an 81-83 EFI car, and someone has contacted me looking for one. I really do not want to sell my spare EFI parts, but their car has been sitting since mid February in want of a replacement. I feel it would be selfish to keep my spare when someone else is unable to enjoy their Imperial. They are the original owner, and I understand that it is a very nice car. Does anyone have any idea what a fair price (for both of us) would be for this part? I don't want to gouge, but I also need to keep in mind that I may have to replace this part someday myself, and would like to have fair compensation. Has anyone bought/sold or seen any of these for sale? It is hard to set a value on something when so very few seem to change hands... Thanks for input! William
