Please note that I do not recommend that you seek to purchase the 3-Lane Super Speedway. My unit stopped working after making this one video. Other Hot Wheels fans and collectors have reported the same failure. I do have a second video but It's because I had originally bought two sets. It is not the same box. While I make it seem fun to own and it's a fun video to watch, I do not recommend you buy the Hot Wheels 3-Lane Super Speedway. Here's that other video.

Can this track be expanded? I answer this question in the following video link:

It reminds me of this Tomica set:
