Maruti Suzuki Launched many car in entry segments. like: Alto, ritz, celerio, swift and Baleno. If we talk about the low cost car then most of the people like Alto based on there price range and all. But my personal advice and experience says if you are looking for low cost car with comfort then please go with Maruti Celerio. Celerio is available with AMT also. AMT means automatic transmission. User not need to change the gear w.r.t speed. Vehicle gear will change automatically by sensing your vehicle speed. No clutch pedal is present in AMT variant. So it will be more comfortable for long drive journey. The look of this vehicle is very sporty and it gives a superior feeling. If we talk about the mileage the diesel variant mileage is very good with affordable price range.
