Twelve Hot Wheels Walmart-exclusive Zamacs released so far. I found three of them in store. The most recent three. Hooray. The other nine came via ebay and friends, but at least I have all twelve.
I am not sure why the Zamacs have been so hard to find. Sure, the hoard epidemic has affected the Datsun 620, but on top of that, it seems not every store gets them. I guess keeping them a little more exclusive ultimately is a good thing, but these last three are literally the first I have seen in store. Maybe its a geography thing. Thankfully there are other ways to get them.
It is my intention to keep collecting the line. I have every one releases since this current run started a few years back. The Zamacs have become a nice cross section of models that Hot Wheels has done the last few years, and they look fantastic together. So, as long as they keep making them, I will keep collecting them. Provided, of course, they can be found.
Here is a 2018 Zamac Update. Six more to come:
