I still have some of my old, original steel Tonka toys that I played with as a kid plus about 15 yrs ago I started collecting Muscle Machines in the 1/18th scale.
My local Wal-Mart quit carrying them for some reason so I quit collecting them but I see they are, or are getting quite popular on E-Bay.
