Q.Used Car in the price range of Rs 4-5 lakh

I assume you are going for the petrol variant. Swift is a very capable car, the 1.2-litre petrol motor is punchy, refined and fuel-efficient. Downsides are the cramped rear seat and insufficient boot space. And the lower end variants don't come with airbags or ABS. If all these are of concern to you, do check out the Maruti Baleno. It gets dual-airbags and ABS as standard across all its variants. It is much more spacious than the Swift and gets the same 1.2 petrol motor. Do check it out. Baleno prices start at Rs 5.25 lakh (ex-showroom, Delhi).
