I purchased this car 4 years back. After driving for 25000kms I am giving this review.
Pros: Refined engine,mileage,low maintenance, very spacious interior, good breaking system. Always satisfactory service from Maruti including free pick up. It has very good pick up and achieves speed very easily due to it's low body weight.
Cones: Suspension sucks. Really disturbing you in bumpy roads. I struggled a lot during my wife pregnancy days as we cannot expect all roads to be in good conditions in India. In highways upto 85km/h, it's comfortable drive. You loose confidence once you reach 100km/h because of low weight- this you can ignore if you are a safe driver. Safety is 2/5.
Verdict: If you have more budget go for Nexon, Jazz, City etc else you will be a happy person with your Dzire.
