I think its sad that the victim now seems to be on the, rather unfair, end of further victimisation on here.
Its clearly a troubling time and its not always possible during these to see the wood for the trees.
OP – Its clearly a terrible situation. Have you spoken with CAB? Whilst there is a little back and forth – cancelled cheques, address changes etc – its imperative you get your timeline of events detailed so that you have an evidence base to show if there isn’t an amiable outcome (this looks unlikely).
The vehicle is still yours. If its in pieces now then is this not a case for the police?
