How to program car crash sounds?

I am designing the sound in a project based on the vehicle preset. Thus, I don’t know how the physics work and I don’t know which properties to alter in order to fix my issue. However, I’m supposed to be given a nice and detailed vehicle provided by I-hope-to-be-my-future-employer. So far, I’m just trying to figure out how to program sound. When I get the new vehicle, I’ll focus more on details.
I tried using DoOnce which is reset by a .2s delay. Still doesn’t sound satisfying. I’ve been focusing on racing games like Forza or Need for Speed for some references, but the problem is I can’t recreate the programming well.
