Suspect its hard to see your pride and joy all bashed up, but if its got a lot of goodies on it, think I would buy it back from the insurance company.
Know youve got to have somewhere to store it, plus the cost of moving it, but if you sell off, or keep the bits and swap on to another car could be most cost effective.
Think if its an own fault accident you will have to pay the ins excess, and hope you have protected no claims, so that next time you have to insure you keep the years you have.
You sure there hadnt been an oil/petrol spillage on the corner, specially as the other car came off at the same place. Just seems a bit of a coincidence!!!
Hope your getting over it OK.
