How much is a parts car worth?

[pizzachef]

Today I'm bummed. I think the insurance is going to screw me on the value of my car after being rear ended in the snow and then the guy left the scene. Its detailed a little more in theis thread:
First road trip observations...

Anyway, I might have to retain the services of an attorney to get what's fair.
The insurance's independent 3rd party car value figure-outer
is saying that a European market car, or grey market car, is worth the same as an R-Title car or salvaged car or TOTALED car...they're trying to say the euro's are worthless. Well, they're still figuring it out, but I'm afraid they're going to offer me about $900.

Regardless, there's damage at the drivers side rear corner, could be straightened but it may not be worth it. If I take money from the insurance company and then sell it as a parts car (or dented but perfectly running car) how much should I expect it to fetch? I can pull the bumper out and put a tail light on it and it'll pass inspection...if that helps mmy cause any.

I appreciate the insight.
Thanks,
