Best of luck for the Purchase !
try buying the Owner name car which the real owner is selling instead of 1st owner car sold 100 times but never trasnfered.
If the real owner is not available, the car is Fishy and anything can be happened in future, if its get trasnfered on your name but still you would never know how the othr person get the car, either few family disputes can bring back the car to real owner and buyer need to find the person whom he bought from it.
So the Owner selling the car on his name is more Reliable then all those 1st owner AKA open letter cars, AVOID them.
Best of luck for Purchasse, Just check Body for any major accident, Engine , tramission, tyres, battery.
Nothing more than that. Few scratches are part of our country where any Rickshaw bike can easily touch it . you can fix it in future but car must be running smoothly and giving you pleasure of what you are paying for it !
sorry for TYPO
