I'm looking at changing my 2013 petrol Renault Clio 0.9 TCe for a diesel as my commute to work is now 134 miles (67 miles each way). I make this commute up to four times per week, however, in a few months I will only be commuting three days per week. I was looking at the Audi A3 as the MPG is better than what my current car achieves on the motorway. However, with the recent press on diesel cars, I'm not sure if I should invest in the A3 e-tron or if it will still be more cost effective to get a diesel. I just don't want to be in a situation where I will face higher charges to park the car or be banned from driving round cities. I can charge the e-tron at home and at work.
