Even better yet... do a web search for Tomica BitCharG R/C cars. I went to the orient and saw these and had to have one. I bought a white Skyline R32 which is the size of a matchbox car but is remote controlled and has different motor choices (race or cruising) and different tire choices (race or cruise) even a front swaybar! The also had lancers and a few other models. These things kick ass =)
