Did you think if he was slim the damage would not have been as bad
LoL. No seriously sorry to hear about this. I will tell you just like mentioned before to file suit, he is not covered on his mothers policy, in general it is to my understanding that he basically violated the law with the exception of New Hampshire unless things have changed. He did not get ticketed but should have if he was not on the insurance card or policy. He is also very lucky he did not injure you or anybody else for that matter. It would have changed from a civil offense to criminal and most likely would have been arrested. Make sure you get checked out by a physician because even though you may not see or feel any pain right now, it could later develop over time and the specific underlying cause could've been this accident. I would also try to get back with the police department to push the issue to get him fined/ticketed so you can have a stronger leg to stand if you or your inusrance company decides to file suit. These kind of things take time but will be worth it in the long run. IMHO I would not replace a Nismo bumper with anything but a OEM Nismo bumper, that is just my OCD. Really it depends on what you want and can afford. USAA usually cuts the body shop a check to repair the damage. I have been with USAA for 16 years and they are really good about taking care of their customers. The main thing is that you are ok and no one got hurt, although it sounds like pork chop could use a diet, and better upbringing/morals as well as driving skills.
