I went through a small broker who put me with Zenith Insurance a few years ago and I've never been able to beat them yet. Fully comp on a 749s, they know all about the carbon modifications and will repair it with carbon goodies in the event of an accident, I have that in writting. Protected No claims bonus. Including uninsured loss recovery. And I have 6 points for speeding.
£300 .... would have been £270 ish without the points.
Broker is Profile Insurance Northant's 01933 410665
Over £40 cheaper then Ducati Insurance services for the same policy and they would not recognise the carbon body work.
