In the Uk we have a plethora of price comparison sites for car insurance. For my 2017 QP quotes vary from £600 to £1000 but the detailed cover will vary. I pay £860 with Chubb but the critical element for me is that it includes full recovery throughout Europe which as a separate item would cost £2-300. It also includes track day cover which I do not take advantage of as on a Ferrari track day I once did a set of tyres in a day!!
It costs a bit more to pay monthly but not a huge premium
