But anyways, I am NOT talking about slot cars. Tose aren't any fun. I am talking about precision RC cars that don't run in slots - they go anywhere. They small, run on batteries (so they can be used in doors), are very very precise and very fast. They make slot cars look like kids stuff. The cars are not toys and can can be pricy $80 - $150, but they are well made, very durable, and last a long time. They are not easy to drive - it takes some time. Look up Mini-Z by Koyosho. They are not very common in the US and can be hard to find, but in Asia, where I first saw them, they are a rage.
