When you first start out insurance will always be high, it has much to do with experience, type of car(looks like you drive a pricey one), gender, and how your record is to start.
Now: 2006, Full Coverage required by loan, $78/mnth on a 2000 Ford Focus LX. This was $35/mnth higher when I lived 5 miles away in the major city in my area.
Then: 1998, $160/mnth on a 1982 Chevy Chevette, nice little beater that eventually rusted to much to be worth fixing. This payment stayed almost the same for 3 years, dropped $5 a year.
Note: I have never been in an accident that was my fault, MA had "steps" in which I was the lowest just before they changed to "points"...either way, I'm at the lowest point.
EDIT: didn't realize you are from the UK, don't know how much of this applies now. sorry lol
