When my 88 got wrecked...I was lucky I got hit by a USAA user. I told USAA we could handle this like adults and give me a fair settlement or we could go to court and it would cost them 50k just to defend it. I told them I knew it was an accident but, through no fault of my own...my situation changed. I got 35,000 for my truck, a week off work and medical...but, my insurance covered all the medical.
In your case the person is luck no one was killed...head-on collisions suck.
thats the way it should be. You should be able to bring your truck to the same quality or better and have money to spare for time off or anything like that! too many times tho thats not the case.. I would keep pushin til they give in tho, the moment you stop pushing is the moment you end up losing!
