"First off, I think the look of this is much better in person than in the photos. It is also larger than I was expecting. The building process and using the mechanical features was fun. The interactive features of this set are the following, the hood opens to see the entire engine, the doors open to revel the seat and steering wheel on the driver's side and the NOS take in the passenger side. You can move passenger side tank to easily access the shift lever to engage the wheelie stand. The stand locks in place to lift the front of the car off the ground. The trunk opens to show two extra NOS tanks. Each wheel has independent suspension, and there is a steering mechanism on the back between the trunk and the the window opening. The back wheels engage the powertrain and hook up to the engine moving the pistons up and down in rotation as the wheels move. The lines stay true to the car."
