Rebuilding my 2008 Mustang V6 EP01

I have always dreamed of buying a Ford Mustang. But in Europe (Croatia) they are not so many of them, and they cost more then a house. So I moved to Germany, got a job, bought one on a 5 years loan. I had the car for 2 years without any mayor issues. Until April, 28. when my girlfriend ran it in a house wall. It's my favorite car so far and I want to rebuild it. So, let's try to make it better than before the accident.
