Do you own a diesel car? Then this may be the most important article you’ll read all year.

Because it could save your HUNDREDS, or even THOUSANDS of pounds.

Here’s why…

Diesel car prices are falling

The value of used diesel cars in the UK is crashing.

In fact, the average value of a used diesel is down 5.7% since the beginning of 2017.

While the average value of a used petrol car is up 5% in the same period.

But that chart doesn’t tell the whole story.

Because some of the UK’s most popular diesel models have seen their resale value drop by as much as 26%

  • A Vauxhall Corsa, which was worth £2,160 at the start of the year could now be worth just £1,592.
  • An Astra, which was worth £2,949 in January, might now fetch just £2,426.
  • And you’ll currently get just £4,766 for an Audi A3 which was valued at £5,373 in January.

Now the really bad news:

This is just the tip of the iceberg.

Diesel prices are expected to plummet further in the final quarter of 2017. And 2018 looks bleak for diesel owners.

So what’s behind the drop?

UK drivers are dumping diesel. FAST.

It’s been a rough couple of years for diesel.

First there was the VW emissions scandal in September 2015…

Then came reports that diesel engines are more harmful to the environment (and human health) than petrol…

And this year diesel owners were hit with news of a forthcoming ‘toxin tax’, which could see daily charges of £20+ for driving diesel cars in the UK’s major cities…

Suffice to say, the writing is on the wall for diesel.

And savvy UK motorists have been paying attention.

More and more diesel owners are looking to offload their cars, before their value falls even further.

But of course, more diesel cars on the market + less demand for diesel means…

Prices will continue to tumble.

But now for some good news.

It’s not too late to sell your diesel car (yet).

Make no mistake.

There’s only one way the value of used diesel cars is heading. And that’s down.

In fact, once the full details of the toxin tax are revealed, it’s not an exaggeration to say that used diesel cars could become effectively worthless.

But we’re not quite there yet.

There’s still time to sell your diesel car.

And… if you’re quick you might even get close to the price you would have got at the start of the year.

How diesel car owners are still getting up to £1,000 more for their car.

Recent months have seen a constant stream of negative news for diesel vehicle owners. From the VW emissions scandal last year; to new scientific evidence on diesel’s impact on air quality; to continued announcements of ‘toxin taxes’ and diesel scrappage schemes. But this new data shows it is only in Q3 2017 where significant changesin diesel car values have begun to hit. The trends point to this drop accelerating further as the year progresses.

Alex Buttle, director of car buying comparison website, comments:

“Our analysis shows clearly that used diesel car prices are only going one way – and that’s down.

“This year has already been a total shocker for diesel owners. And now that most major manufacturers have launched diesel scrappage schemes, it doesn’t look like it’s about to get any better. Diesel cars are really starting to look like white elephants.

“We are now seeing savvy motorists choosing petrol, electric or hybrid used cars over diesel, and that’s already reflected in the value of second hand petrol vehicles starting to rise. That said, for those purely after cheap deals, it is definitely ‘bargain bucket bonanza’ time in the used diesel market.”
