I went with CIS based on the online figure they were giving me. After ringing them up, they quoted me a figure 35 % less than the online one. If anyone is looking for insurance, try ringing them up, they were 50% cheaper than anywhere else for me.
I then sent them a letter stating that I had cosmeticaly modified my vehicle, (lowered, alloys, skirts, front spoiler, induction kit, exhaust, interior mods) and they replied to me confirming that I was insured with all modifications, for an extra cost of nothing.
Just thought it may be useful to some Cliosport users...
