Yes the cars are being delivered earlier then committed time.
I have came across another case in Karachi (Carachi Motors) Shrah Faisal. With below details
Car booked Cultus AGS
Pay order submitted 6 Aug
PBO received 11 Aug (With tentative delivery mentions as 11 Oct)
Car dispatched from factory 2 Sept.
Car reached the dealership 3 Sept.
1 day for the registration.
So overall the request is served in 1 month. So hopefully they will reach the mark where cars will be readily available and customers will be served on walk in basis.
