I have a blue one that I recall purchasing at a local independent hobby shop when I was a kid. I'm not for certain of the exact year but I am for certain it was before 1980 (1977/78, maybe?). Were these cars sold through other outlets prior to the Tandy/Radio Shack days? The car is in good working order. I have the original styrofoam container and an end flap of the box. I remember it having an interchangable gear (low speed/high speed?). I no longer have the other gear. I'm not for certain what investment, if any, should be made to restore the car. I'm not a collector but the car does hold sentimental and nostalgic value that I would like to pass on to my son. Any advice? Thank you!
