How much would a 86-88 gt fastback pontiac fiero be worth?

[dtrain521]

Near my house theres from what I can see an 86-88 gt fiero. I can't tell what year it is but what I'm really interested to know is how much is it worth. It has been sitting on the driveway of a house for the past 10 years and hasnt been moved, no cover or anything on it. I highly doubt it runs and it has 4 flat tires and like I said has just been sitting there the past 10 years. Therefore I am planning to approach the house and ask if they would be interested in selling it but how much do you think it would cost? Any help is greatly appreciated!
It's not on kelley blue book but I appreciate your answer.
