Not interested? My offer is solid. You'll probably get $300-$500 if you junk it, so I'm offering at least double your next avenue unless you spend the time parting it out.
I know you want more for it. Who wouldn't. But considering how much work it needs, and that it isn't hard to find a running ZX3 for ~$1500 that has matching paint on all body panels, I feel $1000 cash is pretty generous for a car with a blown engine.
