Yeah, like I said, he's just gonna stick to waxing and other detailing stuff. He also said that if the insurance does decide to fix his car, he might just trade it in.
My dad seems to be fine, if he's in pain, it'll probably be because he's had a few back surgeries in a year. But, he really hasn't seemed to have gone through any extra pain since the wreck. I think he'll be fine, as it's been over a week now.
UPDATE: Well, he's finally got himself a new car (slightly used 2011 Camaro on September 24), and he actually decided to get an exhaust kit, as well as a CAI. And he plans on tuning it (he got a Cortex that he was using on the G8, he can pay to use it on multiple cars).
And on Monday, he had to go to the insurance's storage lot to strip out most of the nitrous stuff. I guess it's kinda illegal, and the insurance could fine him if they see it in the car when they total it. My mom went there and took some pictures (and continue her rather annoying habit of taking stuff out of the car that we don't need, like the floor mats), and I will say that the damage was way worse than I thought, especially the roof. My dad says that the roof could be replaced, just way too much money.
