Dude, Bro, friend, I am sorry about your INSANE incident seriously. Not going to lie to you, there was a part of your story that made me LMMFAO almost in tears, because I envisioned it in my head like some crazy action scene from a movie.
Anyway I am really glad you are "ok". I quote "ok" because you never really know if you are ok from that type of trauma to the head, years later you could develop something because of this incident. Therefore I recommend getting thoroughly checked out by docs, and get a second opinion as well. I only say the because I had a TBI while I was active duty and it still affects me til this day.
And welcome to the forum!!! It is unfortunate that it had to be like this but now you are part of one of the best car enthusiast forums in the globe IMHO. When you get your 370z you will be very pleased, I am a firm believer that these kind of things happen for a reason. I hope for a richly positive result for you. Take care and get well
