I have heard the same news as well. Still, few dealerships have a booking quota, but you will have to find them.
Bookings will open next month, and probably with a price hike! That’s what I have heard from the dealerships and officials.
As per the source, around 3000 vehicles are booked so far and Suzuki isn’t taking new bookings until next month.
By the way, I booked the car (GLX) on the 1st of March, got a TDD on the 6th of June. This time, there was a complex verification process involved by the company. Initial verification was made at the regional office level, afterwards, the case was forwarded to the Karachi head office.
I think the company is trying to bar the investors from booking cars. I will suggest you follow up with your bank and the dealership involved in your case.
