Hi,
I am currently trying to model the aging of vehicles in a causal loop diagram. I already modeled it in the stock and flow diagram but I am struggeling to modeling the suitable loop diagram for this behavior.
Please refer to my model attached.

What are you struggling with?
I've re-drawn your stock and flow diagram so it's a causal loop one, see view 2 in the attached model.

I think this is the kind of situation where a CLD is not very helpful as a description of how things work. The stock-flow picture is just better.
