Justin, I'm so sorry, definently misfortunate, I'd probably be in tears if this happened to me after a rebuild. I personally know what it's like to get hit by a careless driver too, so I know where you're coming from. The damage might not be replaceable, the damage looks pretty extensive. I would say file a lawsuit against NAPA, due to their negligent driver. remember to tell them all of the damage on the car, and more importantly, how much your body is aching. You'll get a very good amount of $ and you could, dare I say, get a new MK3 if yours is beyond repair.
