Hello there,
I am now planning the replacement of my Maruti Suzuki Ritz and dad is insisting to sell it off before any problems start up. The car still has that charm as when it was new. According to him the mileage is getting poor.

So the choices in my mind are:

1) Maruti Swift ZDi
2) Maruti Ritz ZDi
3) Toyota Etios Liva GD and
4) Volkswagen Polo TDI.

Please do me a favor of identifying the best car out of the four.
