Help me price a sonata with bad engine

[xveganxcowboyx]

I know this is a stupid thing to ask on here and I'd go nuts with research if I had the time, but....

My aunt has a 2001 hyundai sonata which developed a nasty knock. Bottom end, very loud, essentially the engine is fried. She wants it gone quickly and asked me if I could sell it for her. Unfortunately I'm a little lost on what to ask for it so I'm seeking a little advice.

Here's the basics: 2001, 4 cylinder, automatic, 61k miles, some side swipe damage (missing trim piece and dimpling in of both drivers side doors). Otherwise reasonable quality. I'm hoping to get a craigslist posting up today.
