total loss cases are settled at 'lower of' sum insured or prevailing market value of same make and model.
in your case, the car is around 3 months old so assume the market value to be near 66-67, you will get this amount in compensation by insurance company (since it is the lower of the two as explained above). no depreciation/deductible in such cases under normal circumstances until and unless there are some specific clauses added in your motor policy
