BCG Interview Question - Understanding

At a high level, I would imagine that they price an allocation of operating costs and the cost of depreciation into the first 300km driven. Every mile driven thereafter could be just a function of depreciation + previous profit margin.

To understand this a little better, I would probe into the costs per rental and develop a margin for the first 300km. After that, you can come up with the price based on depreciation of every next km + margin (%).

By no means is this the only way to think of this problem. This is just the approach I would take given the information.

Unfortunately there is not more information.

I got it from this post: https://www.preplounge.com/de/consulting-forum/bcg-real-life-german-office-news-here-146

Well we have to note that cars have an accelerated depreciation whereby the car loses bulk of its value in its ifrst few years. Therefore the costs assiigned to the car should be different for different phases. To achieve the same profit margin, the price charged would decrease as the car age.
