Hello @pwuser152598689011
Part are available and you can find them in Lahore easily. Yes the parts are a bit costly.
N-WGN is a market car and it has resale value. Nissan is a good car but you won't see much cars as compared to N-WGN. The drive is way smooth in n-wgn. I drive daily around 2 hours normal and I never get tired.
Also, these cars are imported so local dealerships are not applicable as-far I know.
