It isn't worth putting an old car like this worth no more than a few hundred pounds through www.sure-sell.info. You could try www.webuyanycar.com If you chose to try to sell it yourself, start with a newsagent's window. But be aware that anyone who wants to 'test drive' the car will probably not be insured. Further advertising probably isn't worth it. You could end up spending £100 advertising a car for which you can only get £300.
