Bro, don't get everything mixed up or you'll get confused on which to buy. Sort things one by one and it will be easy to decide.
All cars have one or other issues and not one is perfect all around. You have to compromise one or the other. One is like tank but has resale issues, one has better performance but less comfort, one is easy to service but low built quality.
Safety is the first preference and you don't know how bad things come up so make sure your car is good for worse times. i.e Airbag, ABS
and etc. 6+ lakhs isn't a small amount to ignore these either.
As of service center is concerned, visit every car dealer as well as their workshop and see how good they are. You can also ask car owners who have come for their car servicing about the service center. So that you'll know how good that car dealer is. Akash1886 can also help you this.
But assume if someone says xyz car service center is worst his city is the same in your city. i.e if I say my xyz car service center in my city is not good then it doesn't mean every service center of that car brand in India is bad. Here
is the car specification comparison list may come around your budget and have airbags, abs
and etc safety features. Take a look at Etios Liva too. Renault Pulse RxL ABS
also looks good in charts but I don't know other things of it.
Best of luck.
