I made a discovery the other day about how to glitch the comparethemarket website. When looking for a quote answer EVERYTHING truthfully then when it comes to add a modification add that you have BRAIDED BRAKE HOSES on your car, make sure its Fully comprehensive, upon your search a company called "eCar" should provide you with a quote for less than £200...more specifically £183.75. Others have come up between £200-£300. I don't know if comparethemarket.com does quidco or not.
The braided brake hoses cost about £50 and installing them won't be expensive either.
Give it a try and let me know how you got on.
Be quick, glitches don't last long
