There is no discount on Tiago still. Though the SM assured me that there will be some as they must clear 2016 stock before bringing in newer stocks. According to her, Tiago sales is great and I have personally felt that other manufacturers are feeling the heat already (including Maruti) and they are simply saying that their cars can't be compared with Tiago.
Is there any other point that I should keep in mind while negotiating with the dealer about a 2016 manufactured car?
