Query: Very poor quality control

The bus would not move when we started playing with it, and I quickly discovered why. There was no clearance between the soft body of the bus and the wheels, which prevented them from turning. Because the wheel wells are molded to cover more than 180 of the wheel circumference, raising the body to provide clearance was not an option. Because I didn't want to disappoint my son on Christmas by telling him we had to return the toy, I ended up cutting the case (which is soft plastic) to provide the necessary clearance for the wheels to turn. It doesn't look as good, but at least it works.
