A very warm Welcome to The Automotive India. Congratulations for cracking the IIT-JEE. If its only driving pleasure, then go for a Fiesta Classic right away, but then, you need some style which somehow is a bit less in Fiesta since it has been around for quite sometime. Secondly since you will be keeping the car for the next 7 years, i would suggest you to get some newer model so that you dont end up having a car which looks dated.
I would say, do wait for the new launches like the new gen Swift, and some more sedan which may launch at the end of this year or next year. BTW
what is going to your monthly running and the fuel option you wish to have?
