Do filmmakers crash real and expensive cars in movie stunts?

Not at all if the producers do this, they will come on the road one day.

As soon as I read your question, I remembered Saif Ali Khan and John Abraham's film Race 2.

A scene is shown in the beginning of this film where as soon as Saif Ali Khan unloads his luxury car, his car is immediately blasted.

If you stop this video and watch it carefully, then Saif takes off from the car, then expensive and stylish vehicle appears but as soon as the vehicle is blasted, the vehicle is replaced.

The moment the trailer of Race 2 was released, at the same time, mimes and jokes started to be made on it.

It was just a scene that happens with so many films, we need something else to see but something else is shown to us.
