This is a rare find. The Blue Box brand was exclusive to Woolworth stores. The Roaring Speed Sounder series was a one year only series. Given the millions of kids that had Woolworth toys, these have become quite collectible.

Released 30+ years ago, this is a beautiful Mercedes-Benz SL and it's still in the original packaging!

  If you collect Blue Box vehicles, Mercedes or BlueBox/Woolworth this a great, very hard to find SL for your collection. (1:64 Scale)
