Hey all hoping someone can give me some advice, I've just joined as I've just taken delivery of a 57 plate GT TDi sport

she's a beauty. I've just added it to my current insurance policy which is with tescos, my renewal is due in a months time and they're not being very competetive with my quote. I have a clean licence, I'm 28 and live in Cheshire so not a high risk area

They are quoting me over £1000 which is rediculous at my age or at least i think so. I saw that advert on TV for moneysupermarket (I've been trying to ignore it as it's a little annoying) I had a look on their page
http://www.moneysupermarket.com/motor/ and found tescos are quoting me much cheaper than my renewal, several hundred pounds. Does this quite often tend to be the case if you look online? I was also wondering if there are any specialist companies you could recommend to try? Any help would be much appreciated. Also looking to get it chipped or use a piggy back device like the ones tunit in lancashire do

has anyone got any experience with these?
