Two months is the maximum possible time; I may get the car by the end of March or the first week of April, depending on the production status.
Yes, I have received the booking form but I will get the booking number by the end of this week (probably).
In key to key exchange program (if the vehicle is not readily available and may take some time in delivery), you have an option to sign a contract with the Suzuki dealership (after the evaluation of your current vehicle, condition, price, etc.) and hand them over your vehicle documents and the difference in the amount of the car that you are willing to exchange with. You can keep your car until you get the delivery of your new car, but they will re-evaluate your car condition, mileage, current market value, etc.
Since I was not using my current vehicle, I handed it over to them.
