Until this last year I have used the IAM insurance agent in Norniron. They have/ had a deal with Aviva that allowed them to match the lowest price I could get elsewhere and the policy they offer is a good one with a reputable company. So our car insurance and bike insurance has been cheap even for the Lotus. The latter was usually below £200. In fact the insurance deal is the only reason I have kept the IAM membership going and still do.
Unfortunately they baulked at the latest toy cars value.
