What's My Mustang Worth?

Hi, I was just looking at other Mustangs simillar to mine on the web, and I was just wondering what you guys would apraise it at?
I know it's hard to apraise something you've never seen, heard, or test driven, but I would just like a ballpark figure if you can do it.

Here's what I have:
1987 Mustang LX hatchback with 165,000 miles
2.3L EFI with 85,000 miles
Original AOD auto tranny shifts good!
Considerable rust on rocker panels, behind doors, left rear quarter panel
No hatch spoiler (wing)
Worn carpet and seats
Dash has no cracks!
Currently gray primer and IH blue paint
I really like this car, but it's got some problems I wasn't aware of when I bought it. It only starts if you jumpstart it.

Thanks dude! I payed $300 for mine. I hope if I can get it running decently, and find what I need to make my mods, I might be able to ask between $500-$800 for it. Imagine a LX hatchback on a Jeep CJ-5 chassis with a 302 and 4 inch lift kit.
