I drove V2 for 75,000 KMs in just 1.5 year. It didn't do any abnormalities. It performed better than Pakistani cars.
About spare parts, everything is available at their dealership. I had a minor incident of broken CATconverter, which they installed for free because of warranty. One thing that is great about V2 right now, they are trying their best to beat Suzuki. They will do anything to satisfy you. CATconverter doesn't come on warranty but they installed it for free.
