Bought a swift DLX late last year. No major issues so far.
I do get a clucth noise after driving for extended periods of time and it goes away when i park for a couple of minutes. It is a lube job issue form what i have been told. Waiting for 5000 km free service to get it checked.
I get 500 KM on full tank. By full tank i mean i fill up as soon as the petrol light comes on. And its been like this since the day i got it (with 10%; i.e. 490-510). Done 2250KM so far (thus ~5 refills at the gas pump). The good bit is turning the AC on recently has not spoiled the fuel eff. greatly.
Hmmm.... What else? Nothing that comes to mind. It is a great car. Sometimes i wonder why Suzuki can't imitate the general parts quality across the line.
I can only compare it to City 2011. The City has more cabin space, boot space, the engine is definitely better (in terms of technology and a bit on fuel efficiency). The rear seats have A/C ducts for feet which is really cool. Apart from that their are aesthetic differences like plastic bits on Window rubbers etc.
The cabin of the two cars is similar -cheap and plastiky. Swift's dial cluster is better IMO, but this is a moot point. The city has KPL indicator in the trip meter. I also like the opening mechanism of Swift as comapred to the City (the ugly key hole on the boot is an eye sore on the city).
But the city lacks Alloys, fog lights, RFID security system, 2DIN/4 speaker stereo. All of these things will cost money and raise the price of city to >2.5lacs, the current difference in price.
