when did you get that quote on a 1.9d ? was it an actual van or the estate car -
the vans are astronomical but the estate car is cheap to insure ! try a 1.6HDI berlingo estate CAR (not the van derivitive) - they were about 1/8th of the price for me. 250 fully comp for me on an hdi berlingo car vs 450 3rd party on the van - 1000 on fully comp ! 24 with 3 years NCB !
Current quotes are STILL 450-500 at 25 with 4 years NCB ! glad i dont need to renew till may next year - i was just curious !
