Here is what Toyota says about it;
1. It applies to 60 days after Initial booking (partial payment).
2. KIBOR+3 Yearly ONLY on the BOOKING AMOUNT.
This should result in significant penalty.
If car is booked on 10lacs, Kibor+3 is 15.94% currently. So it will be 159,400 yearly, or 13,283 monthly or 442.7 daily.
So those who got City after 10months should get money for 8months extra time meaning 8*13283 = 106000.
