As far as I know the parts are readily available. You might also take comfort in the thought that the V2 is almost like a Frankenstein of cars, it takes design inspiration from several different cars so a lot of the parts are in the market already. Genuine parts are available from dealerships, any parts that aren't readily available can be ordered from Karachi and they take care of it for you. I remember when FAW first started marketing their cars in Pak, someone complained that their cars are too expensive given that it's a new brand trying to establish itself. They said they will compensate for that by making available parts on the cheap. The experience with the Islamabad dealership has been mostly good. I recently got the 1000 KM service done and though it was a Saturday and they were packed, they accommodated us. I was having a slight issue of brake squeaking which was going to stop anyway after use but they opened the parts up and cleaned them for our peace of mind. I was worried so I contacted head office and they were very helpful too. I hope this helps.
Please feel free to ask if you have any other questions.
