This is my very best creation so far. It is Really Cool and eXtremely fast. First thing's first though, the parts list below is not very complete. There are also 2 RCX Rotation Sensors, 2 Power Functions Motors, 1 Power Functions Pair of Lights, 1 Power Functions Rechargeable Battery Box and 2 RCX Lamp Bricks. With that said, I present to you, my RCX Pneumatic Car V2.0. It has basically everything except for suspension, and it is the fastest %100 unmodified Lego, automatically compressed pneumatic car I have ever seen. Click "Additional Information" to see anything and everything about this car. Also, this seriously needs a "Are you sure?" pop-up before deleting (that's what I get for using a mobile device).
