Hey dude, really sucks when shit like this happens, similar thing have happened to me but not with the skyline thank god. If he has admited fault, lodge a claim with your insurance and say the father admited fault and go from there. Basically as I know, as long as he admits fault even if it is your fault he is responsible.
I think in this situation technically you are to blame as you didn't give way, I know it sucks ass, I had to foot the bill when someone (paper boy) drove into my mates driveway as I was reversing out, I was watching the side mirror to make sure i didn't run over the plants (curved driveway) and he drove in behind me and just stopped and i hit him, this was still on his property mind you and as the law sees it I was at fault cos apparantley I didn't give way he was stopped i hit him.....long shit fight over that one and I still came out worse off.
My advice, just be nice about it all, don't try and rip him off or anything as he has already admited fault and hopefully it should work out ok for you.
P.S: If this doesn't make sense it's cos i been out all night and i can't sleep now.....
