Wow! Glad he survived the accident. That would be a tough call on whether to repair or just get something newer. The idea you want to fix it already says you have a sentimental attachment to it. If the numbers work, go for it. As you stated you never really planned on selling it so the Salvage title won't matter to you if it's fixed right.
Part of me wishes I would have kept my C5 now after it was totaled.
Good Luck with whatever route you decide to take.
