Sad story for sure, I can only imagine how you must feel to see that beautiful car go up in flames.....
Now there are a couple of things I'd suggest:
1) if you get the software recommended earlier, please post some pictures of the car, damaged and undamaged areas so we can comment on what looks rescuable (is that a proper word?) and what probably isn't.
2) as for current value, the truth is likely to be that the parts are worth more individually than as a complete car. But a good ballpark place to start may be the valuation that your insurance company put on the wreck i.e. what you bought it back for. If they paid out the appraised or agreed value as a total loss, then they know what it was worth and would have tried to recoup as much of that as they could.
3) people are probably only asking after the car because nobody wants to see a previously-beautiful classic in a sorry state.
4) you obviously enjoyed the car, and while it may be unpleasant to look at it as it sits today, as a number-matching car, it deserves to be returned to it's previous condition (as you said). Have you thought about getting it professionally restored, more costly that you doing it, but you won't have to put yourself through tearing it all down and doing it again.
Hope this helps, and look forward to pictures!
