Isn't that also true if the engine and transmission also took significant road damage and requires replacement on an ICE BMW?

Breaking news: expensive components of cars are expensive.

Crate engines sell for between $3000 and $12000 for cars. Transmissions $2000 to $5000. (Prices from the first source I found, a reasonable sample range but I suspect you can find things outside the range) In stock and ready to pick-up today at a warehouse near you.

So up to $17k in material costs before the many many hours of labor involved.

The high end is large race tuned engines. Smaller engines are much cheaper and all you need.

That is also brand new. Rebuilt engines are much cheaper and good enough

They are expensive, but rarely more than the car is new.

And in the account I read they had simply run over some unknown road debris on a highway. Something most people could imagine happening to them.
