Brother Yaris has no complaints you are biased... Yaris has way better engine, it has three driving modes eco, nornal and sports, it has seven speed cvt which again is superior than city since it comes with tiptronic, it has hill assist, it has stability control.
Front cabin of city is smaller than any other car, yes city's rear cabin is better than yaris, even though, yaris is wider...
City no doubt has better cosmetic features but suspension, engine, build quality, transmission give Yaris a huge advantage over not only city but certain other cars of the league above, like 1.6 corolla, brv etc.
You comments seem to be very immature
