The value of some used diesel cars has dropped by as much as 26% since the start of this year amid a crackdown on older vehicles.
Second-hand Vauxhall, Audi and BMW diesels have fallen most in price, according to research by the car-buying website Motorway.co.uk. The average used Vauxhall Corsa with a diesel engine has slumped in price from £2,160 to just £1,592 since the start of 2017, a drop of 26%.
The average used diesel car fell in value by 5.7% between the first quarter of 2017 and the third quarter, while used petrol car values rose by 5%.
Motorists are increasingly worried that diesels could become near-worthless in years to come as cities ban the dirtiest polluting vehicles.

Other cities in the UK have also debated following London, with plans mooted for parts of Birmingham, Leeds, Nottingham, Derby and Southampton.

Over the past couple of years there has been a constant stream of negative news for diesel vehicle owners, from the VW emissions scandal to new scientific evidence on diesel’s impact on air quality.
