Sears 1/24 Vintage Professional Slot car track?

[FatManScaleDesigns]

I bought one of these off the local craigslist.. I had intentions of setting it up, Now I have far to much stuff in my house and my wife wants one room for her paintings and I have a model room. It was a impulse buy, ill never use it. I am curious what its worth? I just planned to trade it off for some models if I can I just wanna get an idea what its worth.. It's missing the two cars, has only one remote and 3 packs of extra track brand new in boxes. This stuffs gotta be from the 70-80s. Guy I bought it from told me it was from a company called MArx? I can't be sure if that was it but that comes to mind. Any one know anything about these?
