I did the decent thing and tried our supporter - who unfortunately was £78 more expensive than my current insurers. The reason was the value of the car. I really can't influence the price that bmw charge - the car is a more or less full my specced 35is bought Sep 2016 and they couldnt compete with the current insurers renewal price due to the over £40k purchase price.
I did try and the agent was very polite!
