Insurance wise its a write off but the way I look at it its a good one you know its been in the family from new so its worth repairing it properly. I think it looks worse than it is. It has not damaged the floor pan so we can rebuild it!!
I still don't know what went wrong though I was not going that fast. Still at least it was not a Skyline!!
Thanks for the link Spax I have mailed them a list of parts.
