If you don't mind me asking how much do you pay for your insurance and who are you with?
I checked and best I got was:
Ready for it....
......
.....
....
...
..
.
£1850 + £3k excess
or......
£3k + £700 excess

I currently have the 3.0 and this year paid £1,487 + £500 excess (renewed in July). 28 yo, 5 years NCB, 3 points (SP30).
As a test I removed the SP30 from the quotes and they made no difference to the two quotes above.
