I bought a new 2013 Audi A3 which has apparently not been affected by the emissions problem. I had intended to do 20,000 miles per year, but my personal circumstances changed and I have only done 20,000 in total. I do not expect this rate to change in future. In view of the current furore about diesel cars, what would your advice be on changing the car? Sell now and buy a petrol or hybrid, or hang on to it?
