I actually get more than that ($2,916). That number is generous because it assumes the 1.8L gets 30mpg mixed, and the 1.4L 40mpg mixed to determine the average cost per mile. Using those numbers the cost per mile for the 1.8L is $0.11666 and for the 1.4L $0.0875 . It's unlikely most drivers will see the 40mpg with the 1.4L, and many with the 1.8L are not seeing 30mpg. But relative cost savings is there regardless. That's why in the long term the 1.4L is the better buy, assuming all other costs (maintenance) remain flat. But for those on a tight budget 1.4L is more money, so in the near term the 1.8L will always appear to be the better deal. The article appeared to be coming from the school of initial value, in which case the 1.8L is indeed 'cheaper'.
Also, I did some poking around in the hatchback at the showroom recently when getting my oil changed. I'm happier with the trunk versus the hatch, it just seems I can carry more stuff in my trunk than I would in the hatch. It's rare I fold down the seats, or fill the vehicle to capacity. I carry items at all times for work that would effectively eat up all the space in the rear 'trunk' of the hatch, but with the sedan I have enough room for more stuff without having to drop the seats down. The hatch only seems to be of benefit if you stuff the car full of things, or large items, and take advantage of that additional vertical cubic feet.
