if it is missing the lower fairings and tailpiece then you would be lucky to get £400 on fleabay, I've seen standard '16s struggle to get more than £600 in good condition with a full years mot.

sorry, but '16s just don't command any money, I paid £450 for mine 2 years ago with a good quality paint job and 3 mths mot.
