Just reinsured through Sureterm for £424, but have had to remove one seat from my 110SW to bring it down to 8 seats. My usual insurance broker would touch it at all once I mentioned it had an A-bar on the front.
NFU was £765 with Adrian Flux over £1000, all prices are fully comp.
Age 32, full no claims (>10years), 1 no fault accident in 2007, but am in Northern Ireland. As far as I know there is no limit on personal injury claims in NI so vehicles with a large number of seats get hit with sky-high insurance.
