Hi Aine,

In percentage terms, I’d say  the i30 just shades it. People expect a diesel engine in a mid-size hatchback these days, and the i30 is very much in demand. The Yaris, which generally has an excellent resale value, will suffer here because it has a diesel engine. The petrol (and hybrid) Yaris models are so frugal that it’s not worth spending the extra on the diesel model and so second hand prices are pegged at the same level as the petrol versions.
