Just got my insurance renewal through, you guessed its gone up even with my maximum protected no claims bonus. Time to go shopping, having had many supercars i've used Aviva for many years, two years ago my broker suggested changing to Alliance. Their quote this year £1786 with £2500 excess including my maximum protected no claims bonus. By chance I talked to my household insurer NFU, shocked and stunned their quote with all the above benefits and more £866 with £500 excess, lesson learnt!!!
