Swift is overall a great hatchback ! This is my first car and I will actually not recommend to buy a new car as an amateur because during your first year there are high chances that you'll end up in a minor accident that will leave scratches, dent etc on you car. Since we are talking about this let's first discuss the build quality of this car. Yes it's not so great because an alto hit my car at a slow speed and my bumper lock broke from driver side and bumper partially came out ( Not a major thing though. I fixed it back by kicking my bumper. There's unusual space below headlights now but that's only noticeable when you watch carefully ). So honestly speaking build quality is the only average thing about this car, apart from that it's pretty aesthetic, gives good mileage ( 17 Avg. in Hills ), Interior is good and specially that flat bottom steering wheel makes it sportier.
Without posting a very long and detailed review, here are some pros and cons I found in this car
PROS
1) Stylish Looks
2) Good Mileage
3) Sufficient Space for 5 people. Good Legroom
4) ZXI Plus has various good features. I like the stock sound system and infotainment.
5) Performance is very good. You can feel the pickup capability of this car in 2nd gear. It almost launches your car
6) Everything is very responsive. From Accelerator to Breaks.
7) This car really has everything. I own the topmost model of this car and it has almost all the features you'll expect in a good car. Parking Sensors, Reverse Camera, Side mirrors can be adjusted buy a single button etc. So many features that some of them I don't even use currently
CONS
1) Build Quality is Average. Not bad but definitely not great !
2) ZXI Plus isn't really a value for money model.
3) While Putting the car in reverse gear there's a weird noise like grinding of gears that pisses me off. The company says that various of their new models have this and it's normal so I guess it's fine
Overall : Swift is a good hatchback that offers almost everything you'll ever expect in a hatchback. It's refreshing and powerful and as my first car I'm very much in love with it. Haven't really driven it in plains but in case of hills, it still performs strongly.
