Basically, for 12.75 Lakhs, you will get a pretty crapy Reborn. No doubt, it will be impressive from the outside but on the inside, you will be fuming. Looks like the car was in a major accident and the vibration is due to that. Wheel balancing story is BS, call the owner on it and take it for wheel balancing.
If I was in your place, I would increase my budget by 1.5 lakh and get a decent car in that shape or get the old shape civic in good condition if the budget was restricted.
