No, it isn't.
The costs of initial production set-up is amortized over the sales figure so if the numbers are small, the cost is going to shoot up. The F-22 raptor costs about $100m to make (construction cost) but if you add in the R&D, setting up the facility, etc...the numbers shoots up to $300m per plane.
All this because so few of them are made. Maybe when we start producing 1 lac alto per year (including both domestic or export) PakSuzuki will think of that. Besides, having a bigger market next door is a disadvantage as foreign companies would like to make the bigger market as hub and export to the smaller markets.
