Hello,
Firstly it is good that you are considering this vehicle. Let me assure you, with the right driving technique and environment you will get 13 to 14 fuel consumption. I drive it everyday partial highway partial inner roads and i get this average.
Price? Interesting question. Yes some people got it on discount, but some early buyers got it at original value. Please do keep in mind that overall prices of vehicles have gone up tremendously. This is an imported vehicle. Price of a new Vitara from Paksuzuki has also been increased. So these factors play in the resale market. You can get a lower priced Vitara maybe from someone who got it for less price initially.
Keep checking Pakwheels. With a vehicle like Vitara which is not very easily available like Corolla/Civic/City/Mehran, there can be some price negotiation and variations.
Do let me know if you get a vehicle of your choice....and if it is a Vitara or not.
Sorry could not give you an exact figure, but maybe someone else on this thread with a recent purchase can shed some light on this subject....
...but what can help is if you see what kind of vehicles you are getting in the same amount as what you think the Vitara should be worth. That could give you some ideas about what sounds reasonable.
