How many cylinders does Maruti Alto has?

If budget is strictly 3-4 lakh on road price then only new alto, old alto 800, alto K10, Renault Kwid, Redigo are your total options. With the hope that you are not going at high speeds and will keep a watch on fuel consumption, alto K10 is the best option. The new alto has safety features but is not fuel efficient, Wagon R will be beyond your budget. The old alto 800 is also a bargain buy assuming you still get it officially.

I think no

Adjustable Steering is available in the Maruti Alto VXI and VXI Plus variant by which you can adjust the position of the steering according to your requirement.

Yes it does have ac and it is powerful enough to cool the complete car. No separate ac vents for read passengers

If you start practicing with an automatic transmission u can never drive a manual one. So start with manual one,u can easily manage with automatic one. It's like difference between a 5 speed bike, and honda activa. A person whohas always drive n an activa, it ll be much more difficult for him to ride a gear bike

All have powerful a/c ..depends on using it.cabin is small so more cooling.don't put fan all the time .set between 2 and 3 if it is hot inside. zzdown mirrors a little bit so that warm sir goes out.Then you can maintain it on 1 and 2.Use blower fan if it's too humid.Smart adjustment of vents is another trick.try to park the car in shades. Refill ac .,regular check up during services makes it better.

Yes , not power windows
