Does this car have a usable part on it?

As most say, manual Trans parts, some good trim here and there, v8 centerlink, maybe the inner fenders from what I could see.
Not worth $1500 though, maybe just maybe after the hassle of removing it and parting it you might JUST get your money back. There should be more of an incentive for you to buy IE: a lower price. I wouldn't pay more than $2-300 for it tops, unless you really needed some of the few parts it has to offer.
