Case Tips
The important question to ask before beginning this guesstimate is whether we need to estimate used cars in the private sector or in the commercial sector.
We need to figure out the further divisions in the commercial sector since it doesn’t conform to the standard divisions commonly used in the other examples
Demand side approach would not work since commercial markets need to be dealt with at a individual use case level
