I would suggest Honda Amaze, reasons as follows,
- Very spacious sub 4m car in market
- Sedan compared to a Hatchback
- One of the best petrol engine available in market
- Honda's reliability
- Best FE in class
- Very silent engine
Yes, interiors are plain and simple, but most of them will go for style, comfort, space and safety than some cool feature alone.
Also you can check
my ownership review thread for more info.
ALL THE VERY BEST
