Sorry for jumping in late on the discussion, have been busy for the past few weeks. i will try to describe my own experience so you may decide impartially. I was in the same position as you are right now confused between Swift and V2. Finally decided for V2 in the end.
So here it goes..
My requirement was a hatchback with comfortable ride in mind since it would have to be used for the family. My cousin and a few friends owned swift and i have drove it as well. Amazing Car, Good quality.
Checked out V2 after coming to a Pakwheels review of V2 after its launch in pakistan. Went to the showroom and it was just great, exceeding my expectations. I was of the same view "Chinese Maal hoga, Farigh Hogi etc etc". But to my surprise it was great. Didn't had a test drive but came to this forum and read the reviews and they all seem to agree that the drive was smooth and comfortable.
So crossed my fingers and bought the car and its been a month now drove around 2k kms now. Till now my findings:
Great, Comfortable and Smooth ride.
Perfect for city use.
Mileage is not extraordinary it gave me around 14.5 on my trip to lhr. And within city with modest traffic and speed around 80-90km its round about 12/12.5.
Got into an accident(Truck slammed in from the side) but the body is strong and had just minor damage to rear left side fender and bumper. Went to the dealership costed me around 7k for the denting and painting and bumper repair.
Dealership people are attentive and helpful. Parts are easily available through dealerships.
Now the things that i dont like till now is the braking sound which most of the people faced but its intermittent and in no way affects the braking. Noisy cabin and ac fan. But thats a problem for you if you continuously drive above 100/110km/hr otherwise within city not a dealbreaker i must say.
The major point in choosing V2 was that it would have atleast proper after sales support and since mostly new cars dont have any major problems for atleast a few years so why should i bother buying a CAR whose history is unknown to me(JDM). And chose V2 over swith because they both are almost the same cars so why should i bother spending my hard earned money on swift a good 0.4 millions extra for what just Good brand name and maybe just a higher quality interior. Thanks but no thanks. Why dont i use this amount for contingencies if god forbids any thing happens to my v2.
In the end your decision should be about which car gives you more satisfaction when you drive it. if its swift then no argument will be good enough for you to buy a v2, and vice versa.
Hope this might help you in making a decision.
p.s: For swift i would've paid extra on registration and yearly tokens as well just saying
