Maruti Swift is also powered by the same engine as of Maruti Ritz. The advantage of this car is its interior space and popularity amongst the car fanatics.It gives mileage of 12.8 kmpl in city conditions and 16.6 on highways.
Hyundai i20 is also a good car certified by European Safety standards. The car is more spacious as compared to Maruti Ritz and Maruti Swift. Hyundai i20 us powered by 1.2 liter 4-cylinder engine. It gives mileage of 14 kmpl in city conditions and 17 kmpl on highways.
From the safety space point of view Hyundai i20 is a good option, but resale value of Maruti Swift is more as compared to Hyundai i20 and Maruti Ritz. Amongst the three Maruti Ritz offers more mileage and has got stylish looks too.
Maruti has a good and vast service network and there will be no problem of maintenance and replacement of parts at later stage but the resale value of the car might decrease as the company has decided to discontinue the vehicle. Despite this, there will never be any shortage of parts as manufacturers make parts for next 10 years. Also, as Ritz share a good number of parts with its sibling Swift there will be no shortage whatsoever. If you would like to consider, the Indian auto market has many other offerings in the same segment such as Tata Bolt, Nissan Micra, Ford Figo, Honda Brio and Grand i10, Maruti Swift, Chevrolet Sail hatchback.
