ive not seen the SS cars anywhere except for at a toy stand at a sort of flea market. the jada cars came from walmart, and there is also a new maisto version of the challenger, all blinged out, it retails for around 25 bucks. i did not buy one because the only one that they had was damaged in the package. also, on our last trip, we found that the company who made that old and new challenger remote control set has a new "challenger concept" RC car out. it was 48 bucks, and it wasnt very nice, so we didnt get it either.
