Got the renewal quote through the post for the BM 530i from Direct Line. £760 insurance, £26 legal waffle, £82 breakdown. As usual, went to their website to check the price, as they *always* try it on and charge more for the renewal quote. Did this Tuesday last week, quote was £610. Confused.com best was Kwik Fart at £533. Then I promptly fell to sleep and forgot about it for a week. Today I thought I'd better sort it as it runs out on Monday, went back to Direct Line website, and the quote has dropped to £565, a £45 drop in 11 days? Double checked all the details, and they're the same. After remebering to add in multi car discount it dropped another £50 to the second cheapest quote anywhere of £515. Is car insurance really this volatile (7.4% drop in 10 days) or is there something else causing it to vary and my renewal just happens to be at the time of the year things are re-adjusted?
