Yaar aap samjhe nahe. The car you'll be getting in such a low price will be beyond miserable. And kharcha bhi 20k ka nahe hona bear that in mind. Saaray kharcha kar ke aur fit halat me bana kar bhi the car won't sell above 750k [jaisa ke aapko dealer ne he keh dia I will buy around 725k from you after work, lol].
Baaki dekh lein jaise aapko behtar lagay for your ownself. I am saying this just cz I have had a recent experience with 2005 GLi which cost me 740k after a new axio engine in it. I just disposed it off for now with a relative cz market me uska 750k bhi koi nahe de rha.
This is GLi you are about to buy altis... Do the math. This was the basic reasoning behind my suggestion.
