So 12 Lacks is your budget? Right?
If that's the case then go for City Steermatic.
If you can Increase your budget from 1200K to 1300K-1350K then go for 1.3L 2009-2011 City IVTEC.
But remember performance wise City Steermatic would be way ahead.
Steermatics build quality is better as compared to City IVTEC.
Steermatic has a heavy look!
BTW Would you consume 100L on weekends also? Since there 8weekends In a month!
As far as fuel economy is concerned,
Say that Steermatic has an average of 12.5 km/l. (Economy purely depends on driving style. My figures are just an assumption)
You're daily drive is 100KM.
By these figures we get to know that you'll consume Liters/per day= 100/12.5 = 8Liters per day
Your per month consumptions would be (excluding weekends) = 8*22 = 176L.
Now lets add weekends consumption too!
On average you'll drive a max 40KM on a weekend?
Fuel which you would require on weekends= 40/12.5 = 3.2Liters per one weekend.
You fuel consumption after adding all weekends would be= 8*3.2L = 25.6Liters.
Now Let's add your week days and weekends consumption:
So your max limit on fuel is = 200L
Steermatics fuel consumption as per my figures = 201.6L
See, you'll only have to afford 2L fuel more to enjoy Steermatic.
PS. Fuel consumption varies per person. If you're a calm driver then It will definately deliever you more, and If you're a hard footed driver then It would deliver you significantly less to fulfill you speed thrill.
It all depends on your right foot and left hand.
Remember gear changes matter too!
