Manning UK as previously mentioned Mayfair Performance Insurance 0844 49 35 715 Have alternated between these two for last 4 years with my 987S Adrian Flux 0800 081 8989 although they tend to have lots of additional items added in initially (like key cover, breakdown) which you may want to remove to reduce the premium. Plenty of other companies in the club magazine or 911 Porsche World mag; as ever with insurance it's s lottery based on postcode, usage, occupation, etc etc Make sure you get full cover for all factory fitted extras, these should not be classified as modifications. However if anything was added by the OPC ( for instance some OPCs offered coloured wheels for less than the factory option) then these are modifications in the same way as fitting a sports exhaust after leaving the factory.
