Service Cost Breakdowns

Basically what the title says. Either within the game or maybe through an external source that knows all the variables in game, it would be useful to be able to visualise what parts are affecting the service cost in the detailed stat page since we do have a breakdown of where the weight of the vehicle comes from and how engineering and material costs factor into the price of the vehicle. I know I personally have trouble when I am trying to make a car where the low price and servicing costs are meant to be a selling point but I am unable to understand easily what parts of the car are having the greatest affect on it without persistent trial and error.
