This is why it's so hard to get the X20 in Australia and it's not even available in the US. Europe gets the most up to date engines because of the environmental regulations. I would have loved to at least try the X20 but am very happy with the G25 in any case. All the dealerships that I called in Australia said they didn't even have any X20s on order. No one wants to pay the 4k premium and have to pay for premium fuel in addition, which cancels out any fuel savings anyway. It doesn't sound like there's much between the two engines in any case.
