My renewal was also the similar, I did a new quote on the site and it came down to 1200, then I called them up, asked them explain themselves :)
Got a new quote now from them just under 1100.
I would say, at a minimum try the Online quote and also increase the excess to 1000 or 1500 - There's no way you'll end up having less damage than than in an accident anyway - these cars can get expensive to fix :)
Thanks for the thought and interest, I might look at it. But then again I am lazy
In regards to ease of claim (touch wood), I have not had an accident but did make a windscreen claim this year. I wanted an original Lexus windscreen fitted by Lexus and they have no issue, I paid for it and they reimbursed me in a week or two. So on side it was excellent.
