Next time you start a thread please put some more info there.
How old are you?
I'm going to just assume your under 25 with a GTR , like myself. When I went looking for insurance, the only companies that really wanted to talk to me were Just Cars and GIO Customs, anyone else said over 25, or over 30 for GTR's.
Others were considering it but required the car to be not visible from the street.
I have an excellent driving record, this has paid off and I have an excellent premium, if everyone starts doing racing on the track only (nothing stupid on the street) then our premiums would be less
