Wow.......It's never a good feeling to walk up and see your bike in any different position than you left it.
I hope you at least filed a police report. Collecting the paint wouldn't be a bad idea, but even if you were to get is tested you would really need a sample from the suspected car to compare it to. Even then all it proves is that someone with the same model/year car hit the supermodel, not that that specific car did. The police aren't going to do much, but finding out who drove a silver SUV might be beneficial.
So, the big question is will it be ride able to Texas?
