Question about Jamara Mercedes-Benz Arocs

Difference: the more expensive one is bigger, louder, has a starting function.
Same: the body can be tilted on both, driving functions are the same.

The more expensive dump truck is louder for the first time, has a starter function and horn. It is also somewhat larger. With both models, the tipper can be raised and lowered. I bought both models for my three grandchildren. In a small flat, the smaller one is better.
