mate, I would still be cautious with your insurers on this as that represents 50% of your vehicle's value, if there is a risk of further damage being found on dismantling, which there always is, they will err on the side of caution and write it off, but seeing as there is no structural damage they would be unlikely to categorise the salvage into a category where you can't keep the damaged vehicle.
Do what you think is right though, just pointing out a potential pit fall.

If you can get the price down well below what you have been quoted and can stomach the cost then don't bother with your insurance otherwise you'll have your trousers round your ankles at renewal. Remember you will have to pay your excess if you claim too.
Happy days
