We are gutted too.
The car aquaplaned on water, spun, hit a ditch and rolled.
i'm going to contact some breakers/salvage companies to gauge a price for the whole unit. The car was never recorded as written off so that is positive.
I do have space and tools so might end up breaking it.
Im thinking (Could be waaaay off though)
Engine/Gear box 3K
