Buying cheap cars

[Kong]

Any tips on buying a cheap car?

I am looking for something local - Asheville, NC - around $500. I figure worst case scenario if it completely breaks down I can sell it for scrap and get most of my money back.

Craigslist is the only place I know to look. Any other suggestions?

I am trying to find something that Official Kelley Blue Book New & Used Car Values - Kelley Blue Book says is worth several times more than what I pay.

Any danger signs I should look for when checking the car out?

I kind of need something within the next 7 days.
