I bought this thinking it didn't have a motorized drive mechanism, but it turned out I was mistaken—it actually comes with a DC drive system. I removed the motor and gears and am running it as a towed vehicle for the "A Unit." It’s an average product—nothing special but nothing bad—so I’ve given it three stars.
I think it is well-made. I am very satisfied with how it runs. The sound was a bit lacking, though, so I gave it four stars.
