According to my research, it travels 6 km/h

If you order immediately, the expected delivery time is between Thu. 6.7. and Sat. 12.8. (without guarantee).

No there are none

Unfortunately, we cannot offer any spare parts here. The best thing to do here is to contact the manufacturer directly.

The car has an input for external audio sources and a speaker for e.g. engine sounds.

No, the other more expensive model is: Jamara Mercedes-AMG GT R (12V)

Unfortunately, we currently have no information about when the item will be available again and when we will be able to deliver it. The supplier himself is still waiting for a subsequent delivery from the manufacturer and for this reason he had to set the delivery date to unknown. As soon as something changes in this regard, we will post it here. Sorry.
