Well, it depends on your age, NCD - if any and what is a stupid quote.
I have been round quite a few to be honest, I can't remember them all but I've been with Sureterm (not impressed and will never return to them - they play the "we are just the broker" card too often and offer little help with a minor non-fault prang), Tesco, KwikFit, AA, Adrian Flux a couple of non-sequential years and currently, those are the ones I can remember.
