I think the subject of getting a reasonable settlement from the insurance company has been covered pretty well already. I'll just say good luck having that argument because they're in the business of giving you as little money as possible. We all see a lot of stuff on craigs or other places that is clearly over priced. If I was an insurance company I wouldn't use those ads (that you find) as a reason to part with my hard stolen money. As in: what leverage do you really have to make them want to pay more?

As for plan B, keep it and part it out: My first question is how much market could there really be for 01 Park Ave parts? I have absolutely no clue but I don't see it as being a quick or easy process to get your money back. See also: potential crap from the local authorities about the wreck in your driveway.
