You'd think that. But I've had several interested parties (not from here) who - after having made offers - decided to disappear.
I think your haste in disposing of the car has some worried. The car is easily worth what you are asking, unless there are some things you are not disclosing (and I don't mean that in a larcenous way at all). I know I can't understand why anyone would "scrap" a car for around $300 when it appears worth much more.
Perhaps you could post some more pertinent info and pics to help folk, ie:
Pics of Rust
Does A/C and climate system function?
Does Moonroof, trunk, windows, etc leak?
Moonroof and pwr window condition/function?
What shape dash/rest of the interior (pics would be nice)? Dash cracked all to hell, or just mildly?
I think you replied you do not know the condition of the following: Vacuum pump, Timing Chain, etc, and if there is considerable blowby or not...
Leak in tranny is mentioned, but how about the engine? Any oil/coolant leaks?
What condition are the suspension components/rubber?
I know this seems a lot to ask in order to sell a $1000 car, but if the things I mention above are in shape, it is worth easily more, and scrapping it makes no sense. Cap that with a timeline/deadline exerts pressure on a would-be buyer, and it is hard to perform due diligence when the buyer and car may be 3 or more hours apart.
Best of luck to you... Don't scrap it! You'll only be a tiny amount richer monetarily, and regret lasts a long time.
Hell, if the things I point out are ship-shape, I'll buy it just to speculate/flip it... Can you store it for another week or two?
