I've just insured my 2nd Gen 2.4 Hybrid with NFU Mutual. Most companies don't list Alphards made after 2008 and won't consider models not on their database, but NFU Mutual were happy to cover it. Price was £340 for 10K miles pa, 65yr old, in a rural area, SD&P only.
The best thing is that they answer the phone straight away, no hanging on the line for ever, being told your call is important. I would pay extra for that!
