Not GTI insurance but when I last renewed my Tiguan I made the excess £ 0000 and it made nearly no difference to the quote .
I had a horrible experience with AXA when someone ran into my old car and they wouldn't send assessor to my local garage to authorise repair ,but I had done a deal to change the car for a new one, and was driving it , I was in my garage at least twice a week and phoning all the time chasing them up . , 8 weeks later still no assessor , eventually they employed a company from Glasgow who phoned my garage and authorised over the phone Total bunch of At**h****.
