Yes, it was about 5 days to take delivery, if not for the Thane RTO delays it could've been even more faster.
This is Navnit Motors in Thane, they are supposedly one of the largest in Mumbai area and hence they maintain a continuous supply & large inventory. The service was really good. As soon as the car arrived in the warehouse, they let me visit the yard and check colors & conduct informal inspection also.
By the way, due11027 to your question on 16" alloys, you can consider ZXI (optional) model which comes with 16" alloys + complete leather upholstery & few other bells & whistles, the difference in cost is negligible.
I guess, I should also say that I got lucky with the color being available as part of the inventory. I also know of couple of people waiting for several weeks now on specific colors like red, dignity brown etc.
One more thing that helped smoothen the process was SBI, which cleared my loan in 24 hours and hence I had the approval when I did the booking, right after my inspection I called the bank and told them to disburse the loan which happened in few hours.
