While it is a very beautiful truck, with many sounds and many play possibilities, it is excessively expensive for what it provides and includes. The two cars depicted should be included in the package. The sounds are activated by charging the two vehicles (at the front of the truck where they come into contact). Therefore, in order for the truck to function fully, the two cars are necessary (which, as mentioned earlier, are purchased separately). The issue is that comments mention that it comes with vehicles with sounds. In a thorough search, I did not find anything related to such vehicles. The comments about the truck do not mention the scale of the vehicles at all, resulting in my son having a truck (which he wanted so much) without being able to find the necessary vehicles for it, as the product information is incomplete! It is a shame, honestly, to disappoint a child like this! With such a high price for the product (overpriced product), it is only fair for the vehicles to be included. I find it unacceptable that neither the box/packaging of the truck mentions the compatibility of the vehicles.
