That mission is targeting something the size of a washing machine not a car. Something around 5,000kg is reasonable, but asteroids are denser than your thinking.

How much metals are in this 5k kg rock?

That’s dependent on the rock. An metallic asteroid would be something like 80% Iron which is 7,873 kilograms to the cubic meter.

However, the limitation is mass not volume so while an asteroid 1/3 that density might be chosen it’s still going to be fairly compact.
