The third and the fourth cars look real ugly,
Altho mira is a the Generation Coure.
Boon is a direct competitor to the Cultus, If Suzuki plans to keep Cultus, while they still need some competition to compete the Alto/Mehran segment.
As you said Coure is a competitor to Alto/mehran but the cost say that Coure has steped out of it. As Coure used to be cheaper then the Alto and recent price hikes made it cross Altos retail price.
Anyways lets hope for the better.
