So what have you decided buddy?? Including Linea T-Jet , Etios sedan in your list??
Well why are still considering Aveo in your list? You are going to have your car for atleast 10 years and Aveo is already looking dated. The Aveo is not a good seller and so GM may phase it out also in a few years or maybe it will get a new engine and a facelift also , so better avoid Aveo!
And your major driving is going to be in the city , so why do you want to leave out Linea saying its underpowered?? IMO consider this also in your list!
And City and the SX4 were just face lifted so why do call them as 2-3 years old already!
My suggestions: Linea , SX4 and then finally the City as it costs more and lacks few basic features!
And if you plan to wait for sometime consider Etios sedan and Linea T-Jet! VW sedan Vento will mostly exceed your budget or maybe only the base model without some of the basic features will fit in your budget! If brand value matters most for you then consider VW Vento too!
