i wouldve thought that as a legal document like the log book,that you go by what it says,because at the end of the day surely the insurance company have to prove in mitigation that you willing witheld information,and all you have done is provide the details that are clearly stated in the said document,personally i wouldnt worry about it,had a similar problem on a nissan,said it was a turbo but under the boonet it also had a fuel injection system done some research and found out it was in fact a zx turbo but the log book said diferently. regards gregers
