Left Column

[malteseracer]

I was making a left in a 4 way intersection. I was the second car in line to do so. The first car went well before the rest of the cars and I moved up. The guy going straight up front isn't moving or paying attention of anything so I figure he's either letting me go instead of waiting for the huge line of cars or doesn't know it's green.
Eventually I go and all of a sudden the guy just guns it at the front of my car (not the MINI yet). I pull back straight, he does nothing to avoid me and slams right into me.
Legally I'm at fault because he had the right of way and now to avoid losing my license because I'm a new driver I have to pay everything out of pocket...including fixing his POS truck which looked like it had hit something well before it hit me (rust spots where paint has scraped off kinda gave it away)
The one I'm driving now is actually my dad's and has a totally destroyed headlight assembly and header panel, his truck had a small amount of damage to the bumper and fender, which had made the directional light tilt slightly forward which is why he wants it fixed...he doesn't want water to get in there. Water is gonna get in there anyway and it looks like it'll match the rest of his truck.
Anyway, my question is now after I spend the $1000 (Which is a lot of money to someone just graduating from HS) fixing both cars because mine is actually my dad's which I have until I get the MINI, what should I do to cover my ass? The last thing I need is the guy asking me to re-fix his truck or telling me that he dropped his arthritis medication during the accident and wants it replaced. She I just make up something in writing saying like "I ________ am satisfied with the repairs to my vehicle and will no longer seek any damages from "me".
