To my thots only one would be coming, Which one is the real question, If its Fit, it would be priced somewhere btwn Swift and City, People would prefer City over it because of the boot etc.
Brio on the other hand looks like a win win car, Since Altos going out, Coures dead, Theres no car btwn Mehran and Cultus. Brio could lead the segment, Since coure was priced idioticaly, i fear Brios prices higher then Coure, But if the price is btwn Cultus and Mehran the car can take over sales of Alto. Which i think is alot.
Or else Alto (or the car that replaces Alto) and Brio can be rivals.
But on a serius note, Please dont compare the Brio to Swift or Cultus,
