Hello everyone...this is my first cleaning car and when I received it I gave it the customary clean and lube that I do everything. It actually came with instructions and it told me that it needed to be hooked up to an engine to go down the track?? I have seen videos where they were running in their own. Can anyone school me as to what I should be looking for? The sponge spins nicely under the carriage and I have noticed that the wheels move freely as well. Don't know if they are suppose to. Any info should be appreciated!
Thanks Chris
