Factors affecting the IDV Value of your Vehicle
There are a number of factors that impact the IDV of the vehicle. Age of the car is the most important amongst them. Simply put, the IDV of the two-wheeler is inversely proportional to the age. This translates to, more the age of the vehicle, the lesser would be its corresponding IDV. So basically, the IDV decreases over time due to the depreciation factor of the vehicle. Here is the table to understand the dynamic between age and IDV.
Other than age, the make and model of the vehicle and the manufacturer are the factors that have a bearing on the IDV.
