I suspect your S90 is an 'original' version, ie: not the 2016 on new model (which would only just be coming up to first MOT). There is another forum area (it is called 700/900, but as the S90 was the roll off 900 version), and best to post under 'sales' rather than 'wants'. Good luck with it, I wanted one (30 years ago ..).
