Ok, this is my fellow HybridZ side:
Man that sux, glad you came out ok. Like everybody else said, the damage doesn't look all THAT bad though. Should be able to fix it, with a little time.
Now for my "other" side :
Not to sound like an a$$, but how fast were you going? Must have been up there pretty good if you can't even mention it in the forum. On, a wet road at that! (assuming the roads were wet, and not just right at the entrance to the tunnel) It kills me how kids, completely overestimate their driving abilities and cars, putting the safety of everybody around them in jeopardy because of a complete lack of mature judgement. Luckily, the only casualty was the car.....THIS TIME. Hopefully the car will be down long enough for you to have time to re-think about how long you want to live and what you think other peoples lives are worth.
Ok, I'm done ranting. Good luck on the rebuild!
