What do YOU want to do... Do you want to restore it? Or do you prefer if its totaled, receive a check and shop for a replacement? It's easy to tip the scales either way, so you first need to decide what your desired outcome is and you can create a plan backwards from there.
A few other questions.....Who is it insured with? Do you have "Agreed Upon Value" clause? If so, what is the amount? This is also a factor if it will be totaled or not, and how much you have to spend on a replacement.
