Car insurance

Is he likely to have written a will himself, or would he have used a solicitor? If the latter, it may be possible to ask a local company if they hold it, and if not, are they able to make enquiries of other local firms.

To the best of our knowledge, there’s no known living blood relatives, and we’ve known him for over sixty years. Nobody has driven either car since his death, which isn’t registered yet as there had to be an inquest, which has slowed everything down. Yes, if everything goes to the government, who cares? But, we still hope to find a Will. He always told us he had written one? Just finding it is the problem. 

It is good of you to worry about the cars but TBH in the absence of very close or obvious relatives and no will then nobody can really complain if something does happen to the cars.

you may find a cousin / second cousin or similar - but that would probably be down to probate genealogists who spend their time chasing these things

How much research has anybody done? Could be estranged family, distant cousins etc who have the right to inherit.
