I am a newcomer on TAI but has been following this thread for some time. We booked our Tiago Petrol XZ Espresso Brown on 21 February, even before official booking was opened. Delivery was promised on 25th and car was available for PDI on 26th. Got the delivery on 27th April. By the time we went for delivery the waiting has shot to 8 weeks for both Petrol and Diesel. Have clocked 550 kms on ODO and it's doing well. MID showing 15 kmpl in city traffic with full time AC. Some vibration are felt only when idling in eco mode and AC on and that too at par with any 3 pot Maruti.
Do post some good pics of your Tiago.
I am the admin of the Tiago owners group and if you are interested, I can add you.
