if he still has it, why not tell him to buy a rolling shell from ebay (one that has a legitimate v5) and use his damaged mini as a donor, rebuild the rolling shell into the mini he once had (but with the rolling shell identity) makes sense to me! and keeps everything legal, then that way ,the damaged shell and the v5 from the catagory A write off can be disposed of accordingly
That isn't legal.
Category A write off is the
whole car is crushed. That is the shell and all that parts that made up the vehicle in its entirety.
If it was a Category B, what you're saying would be fine as it is only the shell that has been condemned.
If the man has his facts straight I'd be on the phone to the insurance and asking what the hell they are playing at as unless this cast iron pipe was heavy enough to crush the entire car flat then they're having a laugh. Has he had an inspector round to view the damage or have they done it over the phone?
Roof damage on a Mini is highly likely to be cause for a Category B write off because they're difficult to repair. Category A while stationary though, much less likely.
