Not trying to be rude but trying to point out that you can't go on here badmouthing people and telling people to shut up. That's not how this works. It's an open forum, anyone can comment and give their .02...that's kinda what it's for.
Take the $1,200 fuel injection kit off, and anything else you can resell and just sell it as a parts rig. It's not worth it trying to sell it how it is and anybody who is going to buy it is going to part it out anyway.
I can guarantee you that nobody is going to pay $3,500 or anywhere close to that for this thing. I even think that the $2k offer you got before was generous in it's own right. And like I said before, sometimes you have to take the loss.
We've all been there and done that, so no need to get mad and start hurling insults because no one is taking your insane asking price seriously. Just realize what you have and sell it at it's appropriate value. You overpaid, get over it. Why would you want someone else to make the same mistake you did?
