One of my very close friends owns a Suzuki dealership and according to him. WagonR ko koi khaas lift nahi karai thee logon ne. Then came Uber and Careem and WagonR was an ideal car for them and they started getting massive orders as people bought them in hundrends and hundreds for this purpose.
As a result there was a temporary shortfall in WagonR because of which many private buyers also when came to know WagonR has increased waiting time now, started buying them instead of the old shape Cultus as in brand new there wasn't any other option available in 1000cc.
So lack of options created its demand and because of increasing own they thought its a good car so the trend continued for WagonR in Lahore atleast and it developed this phenomenon. Unfortunately in the minds of our masses a car is not a hit if it has no own/on and people think iss par waiting time nahi hai iss ka matlab hai koi nahi leta aur gari flop hai
