Every week a Guardian Money reader submits a question, and it’s up to you to help him or her out – a selection of the best answers will appear in next Saturday’s paper.
I have a 15-year-old diesel car in south London. I live in the new ultra-low emission zone, which from 2021 will mean I have to pay £12.50 a day. I could sell it, but it’s probably worth less than £1,000. Will it be worthless by 2021? I could pass it to my 22-year-old son, in Shropshire, but I suppose that’s just exporting the pollution. What’s the best thing to do with an old diesel car?
