I have gone through the ad and pictures. Apparently, the car seems fine, but it's exact condition can only be confirmed after it's physical inspection and verification.
Regarding the quote sister; you and the people may right, but let me share another quote:
"... Manzill aur Raasta btanay walay bohat hotay Hain, magar hath ya ungli pakar k; manzil p pohanchanay wala koi koi hi hota hai...!"
Sister, as I have already said, I do not know the market trends and prices; but the people who are saying that the price is high, ask them what should be the price? Get a figure. And regarding high price or availability of 3rd Generation Vitz in that price range, just ask them to get you the same / similar 3rd Generation (or 2nd generation) car in that price figure!
I can guarantee, they won't be able to get you the car. Just to satisfy their ego, they will get you severely damaged car in that price figure, which they quote.
Apparently, that car will seem perfect and flawless!
