Insurers seem to set out their stall for certain types of customer and car.
There are some bizarre outcomes. I regularly use comparison sites and few a 'direct' ones that are not on the comparison sites, for our straightforward requirements of 2 cars for a professional couple living in a small country town. So how come, no matter how how slice it, I can never get a quote from LV?- who are usually quoted as a 'good' insurer to use. It has happened about 3 times now. Weird.
I usually end up back at Direct Line, although every few years I have to move away and then come back when they give a better offer.
The whole insurance market looks broken from my perspective. The endless chasing of new business with attractive premiums, to attempt to clobber you later, so you shift to another and so the cycle goes around again. It is time consuming but kind of fine for me who is internet connected etc. But older drivers like my mother are not internet connected - I'll bet many are being well ripped off.
