I dunno. My details are similar to yours 32 years old full no claims etc. Only thing is on my policy I have an agreed 3k miles limit. I can up it to 5k for a little more though if need be. Mine came back at around £350 all in this year. Best I have ever had since owning the FC.
I struggled this year though to find a decent quote. I asked a few of the commonly used companies why other people on here, that live in higher crime areas, that were younger than me with less driving expeariance and higher powered FD\'s got cheaper quotes. I got told that its basically a postcode lottery and if you live in a nice weathly area then if you crash its more likley to be into something expencive. Bloody joke.
Then I found REIS and all was good
Oh I was with AdrianFlux and they nearly doubled the premium in the second year. Hence the shopping around. Once I called them back to cancel and told them what REIS had quoted (£300 at the time, before I added cover to drive other cars too) they matched it within 2 mins minus the track days.
