Buying my first car

I want to buy a budget car for around 2L-2.5L. I am inclined towards buying a Volkswagen Polo which are around 8-10years old. Few questions I want to ask the people here:

-if you guys think polo is not a good option then what else should I consider? -is it a good idea to buy a car which is 8-10 year old (I am in Mumbai) -what should I look for generally if I am buying that old car?
