Maybe you have reading comprehension problems, because that's exactly how I read master chuck's post. The dealership obv has better sharks, so why go try to hunt them?The irony of your post...
Car dealerships are a bunch of sharks, but trying to sell it for more than it is worth (AKA ripping them off) to some private buyers is totally cool.
Your post would have been much better put if you said "Dont sell it to the sharks, BE the shark!"
I'd list it for the full blue book value, and the only thing I'd tell anyone about the history is that you got it from some thugs and you're worried that since they have your address they might try to steal the car back. That's only if they ask why you're getting rid of it. After a month or 2, if you have no bites, then think seriously about the dealership route. Meantime, you got the jurassic truck to use as a commuter vehicle.
