You probably own a ciaz which i did but just sold it. So u think it is more powerful than city and swift sure if thats what makes u happy.
I guess ur bias stems from being a 9 yr old model to which i agree.
Ciaz has a much bigger disadvantage : with its price tag it loses out to the cheaper city or if u got the bucks why not go dor GLI.
Go to any suzuki showroom they r practically begging for u to purchase the ciaz.
Advantage no wait/delivery period.
