Too low bike content?

I have eyed a Lemond on FB at $350 see link. I don't need it but the size is right and I can get to it reasonably quick down the road about 1 hour. I don't care about the components but the frame and fork. I would buy a new Shimano Crank and then some shifter and RD and RD. I have the rest of the stuff. I don't own a steel bike but it might actually be better for riding inside than my Wilier and actually better or at least safer than the Wilier if I go outside. Worst case scenario is I just sell it if things go add up.
Do I dare make and offer of $250 and tell me if my thinking about the bike is ok and what about the offer?
