Why sports car insurance quote from tesco is lb550 whereas competitors quote over lb1000 ?

i went through swinton, axa ,norwich union, big performance, churchil, and a couple others. they did not even come close...is this possible?

i am a bit suspicious, if that tesco quote is reliable, but they say when i send for that i can complete the whole process online and i do enter the same detail as on other websites.

Different risk assessment procedure. I've been insured near Tesco before, they're perfectly fine to operation with.
Just budge for the more expensive ones then. LOL.
