Adrian Flux offer it.
Hadn't thought of them - I've had my home and contents insurance with them for several years. Went on their website and got a quote - considerably dearer than Admiral or Tesco Bank or LVE.
I have had it suggested that my Caravelle having seven seats is a problem causing cost. Fact is that 90% of the time there will only be two of us in the vehicle, with the two second row seats only being occupied on rare occasions.
I had considered having the rear 3-seater assembly removed, but changed my mind for the following reasons:
(a) this assembly is heavy and, being an expensive part of the vehicle would have to be carefully stored for replacing in the event of the vehicle being sold.
(b) one opinion I received, and which seemed sensible, is that this seat assembly is a valuable second wall in the event of being rammed from the rear.
Someone did suggest that I should have gone for the VW California camper van, which is built on the same base vehicle, but on a like-for-like basis (engine/transmission, year, etc.) I would be looking at around another £10,000. Definitely not an option!
