Take the Citroen C1, for instance. The diesel version does an extra seven miles to the gallon and only costs £1000 more than the petrol. Sounds tempting, doesn't it?
Well, unless you plan on using it for space travel, forget it. You'd have to do around 1.3 million miles just to make the extra cost back. That's nearly three times to the moon and back.
A petrol, rather than diesel, Ford Focus will be the cheaper alternative for most people, too.
A petrol Mercedes E-Class probably won't be, though. You'll have to do 61,000 miles before you make back the extra cost of the diesel car in fuel savings, but many owners will spend a lot of time on the motorway, so they could do so quite easily.
Hmm, the end of the diesel era!'Bigger diesel cars generally hold their value better than petrol versions. However, if the cost of diesel fuel continues to soar, I expect many diesel cars to plummet in value as petrol cars become cheaper to run.'
