13000 CC or 1000 CC ? Which package is it? With climate control? Registered?
I do not know it's worth but as I have seen a lot of simple 2006 plain 1000CC vitz being sold in front of me around 10,20000 Rs to 10,50000 Rs. So, lets take this scenario (which I have seen) as an example. If you buy simple 1000CC 2006 vitz in around 10,50000 Rs. You will get HIDs in 5000Rs. Back view cam in 2000Rs. Fog lights in 5000Rs. Alloy rims with new tires in 40,000 Rs. Sports kit in 5000 Rs. It will shoot to total of 1107000. Let's forget the labor charge. I am also not adding DVD navigation system because the japanease ones do not work here well. But if it is added here in Pakistan then you can certainly add at least 25000 Rs.
Now, this model is 2008. So add 50,000Rs for that. This will go to 1157000 Rs. I think this version is worth if it is with in 11,70000 Rs.
But if it is 1300 CC. It is very close to it's worth.
Do check it for body repaints. The repaints kill the price.
I have also heard that there is a rise in prices of vitz in last one month.
Disclaimer: The above calculations are the result of crude observation of market. Let other experts to give opinion for better view of it's market worth.
best of luck,
