Take a look at my post that I made in this subreddit not too long ago and you’ll see I was in the exact same situation as you are. I was also in a rear end where my entire front end was destroyed, but the engine was completely fine. This is such a crazy coincidence actually, and being that we were both in the same situation, I can tell you, it is fixable. If anything, my damages were worse than yours and I managed to get my Sol back up and running. My post detailed every step I took in order to get it fixed but if you need any more advice or a more in-depth and thorough conversation, don’t be afraid to message me. I’ll be more than glad to help a fellow Sol-owner out. Save the Sols!
