you are good man as i bought my R33 1 years ago from dealer the car showing 56kms but I found a piece of paper in the car saying the car already done over 120kms in 2006 when the car still in japan
Try just car mate. I had a same situation here as well I am a 60% NCB or Rating 1 but my new policy had gone up 25% so i got no choice to change company ^^ wish you find a good deal.....
