My 200 with 2 years ncb - insured it when i was 19, cost around £1600, my 1.2 TCE quote for renewal, was £1400, it hardly dropped. I only jokingly did the quote for a 200, didnt really intend on getting one at that point as I thought it would be ridiculous. But I could afford it so I did.
The annoying thing about insurance is people either buy a banger and don't insure it as the price is 5 times the value of the car, or every time there is an accident people claim whiplash etc, when it cannot be definitively proved. Insurance to some degree is all abit of a con, typically when you do need them, they dont want to help, but they will happily take your money.
