Hi sir i have 2017 model delta baleno. 2 months before i renew my insurance via indus motors they give me 3-75 lakh idv.. And few days back my friend renew his same model baleno he got 4-20 lakh idv.. Then i ask to indus why you give different amount they dint give any reasons.. And i ask 5-6 same model owners they also same complaint against indus and maruti... Some one get 3-60 lakh and some one get 4-40 lakh.. What is the reason.. And one of agent call my friend and ask to renew his insurance via indus he offered 3-80 idv on 2017 model petrol delta but my friend ask more idv.. Last he got 4-27 lakh idv... What is this.
Actually maruti secular following 10% dedection from showroom price but indus cut my 75000 value in a year.. Last year i have 4-50 lakh idv now i have 3-75. Pls give me a valuable reply otherwise i will register a case against maruti and indus.. Already we talk with an advocate.. My car no.. Kl 72 a 6884
