The first problem I see is that it's priced to sell AND it's on barnstormers. This seller is obviously clueless as to how Barnstormers works. You overprice your plane, turn down reasonable offer after reasonable offer, keep paying $15.00/mo for the ad to run, pay storage fees, let the engine sit and rust, pay for an annual and pay for insurance for for a year or more. Then, curse all the tire kickers and lowballers who don't appreciate how clean you've kept the windshield for the past decade and give up on selling it, let the annual and insurance lapse, weld it to the ramp and let it sit for your heirs to deal with.
If you think it's a good deal and something you would buy, go look at it now, it won't be there long. If you're just window shopping, bookmark the page, check back daily and see how long it takes to go away. If it's a good deal, It'll be gone a week from now.
