Today checked for the 2nd time with the marked issues which i had in mind. That picture which i was referring above is not actually a rust. My bad... I checked total 9 ( 3 AT & 6 MT ) grand i10's in the yard and all of them has same welding/mark. So, i guess it is how they've made in factory.
under-body looks clean as well. And Now, We've proceeded for registration.
EDD: Saturday - Monday
Crusier, So true about high demand but that doesn't mean that i have to accept whatever condition the car is. While the battery was my only concern, later yesterday i found out about the rust and thought it is something damaged. But hopefully it is not, I checked this on other grand cars at yard ( white, twilight blue, stardust, winered, orange..etc ) All of them has same markings. The engineer explained, it's a welding joint and that's how it looks usually and mostly it goes invisible when we do the under-body/anti-rust work.
But again, you're right about the prices in 2014 and i don't feel like paying anymore than this for a car with no freaking ABS
and Airbags. It is the sexy outlooks that grabbed my heart and soul.
Thank you for sharing your views and suggestions mate. I have now made my choice and waiting for the day to push the start button with no keys!
Thanks again to everyone out there as well.
I will make a new thread with detailed specs... in couple of weeks.
