I don't know about this 1.2, 1.3, 1.4 business. They are very small engines, even by Australian standards, where we have always had many 4 cylinder options and 6 cylinder 2.5 to 3.0 has always been the norm over the years.
For economy you can't go past them but engines that small don't have nearly the life expectancy as larger ones even the larger 4 cyls. This can be important if you are buying a car a few years old.
For example, I have a Ford, Family sedan (Falcon) it's 13 years old and has done 240.000 kms and still runs beautifully without any sign of wear. There is no way on earth a small 4 cyl will last that long without a rebuild, let alone major work.
Couple this with the fact that sometimes it's quicker to run along side the car.................................lol ;D
