He hasn't had a proper insurance policy in 20+ years. Only the classic car policy in his Defender.
As he had no NCB quotes for his 320d were coming in at £700+.
We found insurance with BeWise for £390 and jumped at it.
For some reason they have his year of birth down as 1962 even though I've checked over what I filled in on moneysupermarket and indefinitely put down 1960.
I've also just had an email asking for proof on NCB. I actually said he had no NCB but because I also said he hasn't made a claim they ASSUMED he had 9+ years.

I can see arguments unfolding shortly.
I shall keep you up to date.
