In my opinion best options are either
- Mira
- Japanese Alto
Parts for Mira are easily available, same goes for Japanese Alto. None of the Japanese imports have good resale, because everyone prefers to get an unregistered Japanese vehicle. Also Mira engine is same as the one in Daihatsu Move, Tanto, Mira Gino, As far as fuel consumption goes Mira manual and Mira CVT or 4 speed auto will easily give you 17km/ltr within city if you drive sensibly. Don't go for three speed automatic.
I have a Mira Custom by the way.
