^Pak Suzuki's main product r small vehicles eg Mehran, Alto, Cultus, Bolan, Ravi etc..Liana is just a bonus for them, to get a share out of the sedan market.
I don't think they ever expected to outsell other brands, but just to get some market with Liana.
Don't think Liana will be replaced for another 3-4 years, as they had to install a separate plant for it..
