Vitz is not a good choice for hilly areas specially 1.0 engine. I own one and i am not at all satisfied with it as i live in islamabad and it struggles sometimes even in islamabad slopes.
Spare parts are available pretty easily now a days in every major city, i am not sure about abbotabad but if we talk about multan, lahore, rawalpindi, peshawar, swat etc, no issue at all. 3s parts are almost double triple the rate of local market.
It won't make a huge difference, you will encouter freight charges etc. try buying local car instead
Auction sheet 4 or 4.5 is considered best.. But they are usually expensive.. It's entirely your decision. But of course getting a 4 4.5 5 grade car is awesome!
