When I imported my new Y elefantino Rosso from Rotterdam the dealers arranged the temporary plates which I think cost £75, and i still have them as they were only transit plates, I also had to specify the route I was taking to Calais.
As far as insurance was concerned I trawled through specialist left hand drive insurers.
Whether or not any of the above is still relevant i'm not sure as it was 18 years ago.
