when i got my re-quote in for my 1st 9 just over a year ago it was £440, i then insured the dc5 for £800, sold it and now its £800 to insure my 9 i obviously questioned how they could justify the 9 being the same price now as the dc5 and they said in the last year there has been a lot of accidents involving 9's, few right offs etc, hence the price has doubled in just over a year.. for me anyway. If people took more care and didnt drive like arseholes and crash them it would be cheaper for everyone.
good luck on your search bud
