Good luck Roger and well done ...but it must be like selling your dog !!!!!...
..have you considered finding the new owner and just standing outside his house and quietly staring...just staring.!!!..until they call the police !!!
When I sold my Porsche 356 I was kindly invited to drive the car on two occasions by the new owner...not sure it was a good idea..they still haven't found his body !!!!...I need my medication nurse!!
