Hey Glen, sorry to hear about your bad luck, real set back, and heartache,
I would have thought that it would be hard to classify a flood damaged car as an unrepairable, apart from the water invasion to all the nooks and crannies of the body and the long term effects that could have, the car is still structurally sound and straight, to me the biggest pain would be completely gutting the car and starting again,
Good luck with it all,
Andrew..,
