Is this fixable

I'm glad your daughter wasn't injured. I gave my daughter our first 67 cuda and she wrecked it. I learned my lesson and later put junior in a 88 Accord. It was wrecked when I bought it. We fixed it and he wrecked it again. No injuries Thank God.
Some of these little cars are very easy to fix ( like the Accord 87 thru 92 ). They are worth the effort too with their dependable engines and all.
I doubt you'll find anyone who recommends fixing that Pontiac. Sorry
The good news is both of my offspring learned a valuable lesson and have never been in another accident. Hopefully yours did too.
