I have been with Headley for 10 years since buying the car. It’s a 2011 +4.
My premium this year excluding add ons would have been £338 which was the same price as last year. I did pay an additional amount for Rescue & Legal cover.
So same year car but yours has a more powerful engine than mine and the premium is roughly the same.
As an additional comment I have always found Headley very professional and easy to deal with.
