As numerous posts have stated over many years on the Forum,
there are many insurance companies that will take your money, and insure any vehicles here.
If  people have a major accident, and try to claim, they will find out that the insurance is void.
Also local ITV stations here are only willing to take your money!
I think it's best to abide by the rules/law in the country you reside in, at least for peace of mind, and to stop it becoming a nasty and costly experience.
