I swear by Confused. It is a bit long winded to fill in the forms but once filled in they will be remembered. I saved £100 and got my insurance down from £260 to £160, fully comp, for a much bigger car than yours. The only difference is that I do not have a legal helpline (never used one in years), I have to pay the first £250 instead of £225 and there is no Roadside assistance but I get this with my bank account. If all the prices you get are similar to the one that you have I would be tempted to stay with it if they are OK. I think £235 is very, very expensive for a Ka but I suppose it is all down to age, points, area etc.
