We're on the same page really because I too am of the same belief that a kei car should not be expected to deliver the same as a higher powered automobile.
But say if your daily commute is 70-80kms tops, average speed around 60-70kms/hr and just one/two people are to use the car at a time for travelling, then in that case I frankly think the best option would be what we are in the midst of discussing.
Thing is my youngest sibling who will be hitting university soon needs a car and a 660cc car perfectly fits his requirement based on his issues with driving a manual trans car in Lahore's traffic + taking fuel efficiency into consideration.
Cuore was an option at first but not anymore.
Like you said about "stick to something that has some backing".... is the reason why I want to make sure the final option I land on has its spares available in the local market.
Further naked truth like Xulfiqar's will be appreciated.
