Owww that looks bad!! Why is it a write off then? Just because of the value of the car against the damage? or Is there structural damage as well?? Also, How did you crash?
If all else fails, Get some people on here to help you, Buy another Mk1, Carry your nicly painted pannels, interiour etc over onto the other Mk1 then see where you go from there
Chin up, Always look on the bright side
